Why Custom Window Box Packaging Wins on the Shelf
I still remember standing on a packing line in Shenzhen, watching a buyer from a cosmetics brand pick up three cartons in under ten seconds. She never opened them. She tilted each one toward the light, checked the window, and made her decision before her coffee got cold. That’s the part most people miss: custom window box packaging wholesale sells the product before anyone touches it. On a retail shelf in Guangzhou, a 40 mm window can do more work than a $2.00 promo sticker ever will.
The window does the heavy lifting. A clean cutout with a clear film lets the product show through, which matters for retail packaging, gifting, bakery, cosmetics, and specialty food packaging. If you’re selling candles with a textured label, soaps with color variation, or cookies with a premium finish, custom window box packaging wholesale gives shoppers proof instead of promises. People trust what they can see. Simple. Annoyingly simple, actually. A 0.3 mm PET film can be the difference between “maybe” and “put it in the cart.”
I’ve seen brands cut returns just by making the box more honest. When the product inside looks like the photo on the shelf, you get fewer “this isn’t what I expected” complaints. Retail staff also like custom window box packaging wholesale because they can face a shelf faster and keep displays tidy without opening every carton. Less handling. Less mess. More sell-through. In one chain store test in Los Angeles, a windowed soap carton outsold the solid-front version by 14% over six weeks.
In one client meeting, a snack brand was stuck choosing between plain folding cartons and custom window box packaging wholesale with a small oval window. Their cost difference was about $0.07 per unit at 10,000 pieces, which sounded painful until we ran the numbers on retail conversion. They chose the window. Their distributor liked it because the boxes merchandised faster, and the brand liked it because the package looked more expensive without adding $3 worth of nonsense. That’s how packaging should work. At 5,000 pieces, the same window added closer to $0.09 per unit because the die and film costs were spread over fewer cartons. Math is rude like that.
Honestly, I think a lot of brands overspend on decoration and underinvest in visibility. A 350gsm SBS board with a matte aqueous coating and a clear PET window can feel premium without pretending the box is a jewelry case. If you’re buying custom window box packaging wholesale, the goal is not to impress another packaging nerd. It’s to move product off a shelf. In Dongguan and Ningbo, I’ve seen buyers skip embossing entirely and still get a better retail result because the window and print contrast were done properly.
Window boxes also help with branded packaging and package branding because the structure itself becomes part of the marketing. A good die-cut window, matched with foil or spot UV, can carry the brand story before the customer reads a word. I’ve seen that work especially well for custom printed boxes in gift sets where the product color is part of the appeal. The box is not just a container. It’s a sales tool. A 20 mm foil border around the cutout can make a $1.20 carton look like a $4.00 one if the design is disciplined.
For brands trying to balance retail packaging and budget control, custom window box packaging wholesale is often the cleaner answer than rigid boxes with expensive inserts. You can get a polished look using paperboard, accurate print registration, and one smart window placement. No need to overcomplicate it unless your product actually needs heavy protection. I’ve walked through enough supplier meetings in Shenzhen and Guangzhou to know that the brands with the simplest structure choices usually have the happiest reorders.
Product Details: Box Styles, Window Shapes, and Use Cases
Custom window box packaging wholesale comes in more box styles than most buyers expect. The right structure depends on product weight, display needs, and how much abuse the box will take from freight, shelves, and eager customers who squeeze everything. I’ve worked through enough packaging design meetings to know one thing: “It looks nice” is not a spec. A box that looks great in a Photoshop mockup can still fail after 2,000 miles in a shipping carton from Shenzhen to Chicago.
Common box formats include tuck end boxes, auto-lock bottom boxes, sleeve boxes, rigid-style foldable boxes, and mailer versions with windows. Tuck end styles are efficient for lightweight retail packaging like soap, accessories, and small candles. Auto-lock bottoms help when the product has a little more weight, like jars or boxed chocolates. Sleeve formats work well for layered presentation. Foldable rigid-style packaging gives you a premium feel while still shipping flat, which saves space if you’re not trying to pay air freight for cardboard. Mailer versions with windows are useful for e-commerce kits and gift sets where the unboxing matters. A 350gsm artboard tuck box is usually a sweet spot for light retail items; a 1.5 mm rigid board makes more sense when the box needs to carry weight and drama.
Window shape matters too. I’ve specified rectangle windows for bakery trays, oval windows for beauty kits, circles for compact products, and full-panel windows for display-heavy custom printed boxes. You can also do custom die-cut shapes if your product shape is part of the appeal. A candle brand once asked for a flame-shaped cutout. It looked great in the mockup. On the production line, it meant tighter tolerances and more die cleanup, so I told them exactly what that would cost. They kept the shape, but they stopped pretending it was a cheap option. The die charge alone jumped by about $180, and the lead time stretched by three business days because the cutting form needed extra setup.
For custom window box packaging wholesale, you also need to decide whether the window uses film or stays open. PET film is the usual choice when you want visibility and a little barrier against dust, handling, or grease. For bakery items, chocolates, and some cosmetics, film is usually the safer route. For dry, non-food retail items like soap bars, stationery, or accessories, no-film windows can work if the product and distribution channel allow it. That said, open windows can collect dust during storage, and warehouse people are not always delicate artists. Shocking, I know. A 0.2 mm PET sheet costs more than an open cut, but it protects product presentation in humid places like Miami, Manila, and Singapore.
Food and bakery brands should think about barrier issues, migration concerns, and shelf life. If the box is near product that can pick up odor or moisture, film selection and ink choice matter. I’ve seen people rush custom window box packaging wholesale for baked goods and forget that the packaging still needs to perform after 48 hours in a warm truck. That’s not a design problem. That’s a failure to spec the pack properly. A bakery box leaving a plant in Dongguan for a Tokyo retailer may need a stronger grease-resistant coating than a candle box sold in a local boutique.
Best-fit use cases include:
- Candles with printed labels and textured finishes
- Soap bars, bath sets, and personal care kits
- Supplements in secondary retail packaging
- Cookies, brownies, chocolates, and confectionery
- Accessories like scarves, socks, and jewelry sets
- Gift boxes for holidays, promotions, and subscription add-ons
Customization options are broad. You can add inserts, partitions, hang tabs, embossing, foil stamping, spot UV, soft-touch coating, matte or gloss lamination, and inside printing. For custom window box packaging wholesale, inserts are often the difference between a product floating around like it missed its bus and a product that looks ready for shelf display. I’ve seen a simple 350gsm paperboard insert increase perceived value more than a fancy finish ever could. If the product is 120 mm tall and the window starts 15 mm too low, a custom insert can correct the visual proportion without changing the dieline.
If you’re comparing Custom Packaging Products, keep the use case front and center. A bakery box and a cosmetics box can look similar at a glance, but the structural and regulatory needs are not the same. That’s where real packaging design earns its keep. Not in a mood board. On the line. A 24pt SBS cosmetic carton and a 400gsm food box might both be “nice boxes,” but they are not the same job in Suzhou or in Ohio.
Specifications You Need Before Requesting a Quote
Want an accurate quote for custom window box packaging wholesale? Send specs, not vibes. I’m only half joking. The fastest quotes come from buyers who know product dimensions, target quantity, structure preference, print coverage, and where the box is shipping. If you send “we need a nice box for our candles,” you’ll get a range so wide it might as well be a weather forecast. A real quote on a 5,000-piece order can move from $0.22 to $0.41 per unit depending on one missing detail.
Start with product dimensions: length, width, height, and any unusual shape details. A jar with a 2.5-inch diameter and 3.75-inch height needs different clearances than a soap bar in a sleeve. For custom window box packaging wholesale, wall thickness and insert needs also matter because the box has to hold the product without crushing the presentation. If there is a display tray inside, say so. If the product is fragile, say that twice. A 68 mm-wide candle tin and a 90 mm-wide candle tin are not “close enough” in production terms, especially when the window placement must land dead center.
Material choice comes next. Common board options include SBS paperboard, kraft board, CCNB, corrugated board, and rigid board. SBS is a popular choice for premium retail packaging because it prints cleanly and holds detail well. Kraft works for natural, eco-minded package branding. CCNB can help manage cost when the outer look matters more than the inside layer. Corrugated is better when protection and shipping durability matter. Rigid board is for customers who want that heavy, premium feel and are willing to pay for it. For custom window box packaging wholesale, the board choice can swing the unit price by more than you’d think, sometimes by $0.10 to $0.35 per piece depending on thickness and finish. A 350gsm C1S artboard with a 0.2 mm PET window is common for lightweight retail cartons; a 24pt CCNB with clay coating is a different cost structure entirely.
Thickness usually runs from about 12pt to 24pt for folding cartons, with heavier structures for rigid styles. That thickness changes how the box feels in hand, how it stands on shelf, and how much weight it adds to shipping cartons. I’ve had buyers request “sturdy but lightweight,” which is fair, but the machine does not care about adjectives. It cares about board caliper and score lines. A 16pt board can be perfect for a 120g soap bar, while a 24pt stock may be better for a three-piece gift set with a window and insert.
Print details matter just as much. For custom window box packaging wholesale, tell your supplier whether you need CMYK, PMS spot matching, inside printing, soft-touch lamination, gloss varnish, matte lamination, foil, or spot UV. If food contact is part of the conversation, ask about food-safe inks, coatings, and compliance requirements. If you need eco-friendly sourcing, ask about FSC paper and documentation. For reference, the Forest Stewardship Council outlines chain-of-custody and responsible sourcing standards at fsc.org, and the EPA has useful information on packaging and waste reduction at epa.gov. A matte aqueous finish on a 4-color carton usually adds less cost than soft-touch lamination, which can be the difference between a $0.28 and a $0.36 unit price at 10,000 pieces.
I visited a carton facility in Dongguan where the buyer had approved artwork before confirming the insert. Sounds harmless. It wasn’t. The insert pushed the product up by 3 mm, which meant the window was off-center once assembled. We fixed it, but it cost two days and a revised dieline. For custom window box packaging wholesale, getting the specs right before quote approval saves time and money. It also keeps everyone from pretending the mistake was “minor.” A 3 mm shift is visible on shelf. The eye catches it instantly.
Here’s what speeds up quoting:
- Exact product dimensions in millimeters or inches
- Target quantity, such as 3,000, 5,000, or 10,000 units
- Destination zip code or country
- Flat-packed or pre-assembled requirement
- Artwork file format, ideally AI, PDF, or editable vector files
- Any insert, partition, or hang tab needs
For custom window box packaging wholesale, the best quotes happen when the buyer has a simple package brief and one or two reference images. You do not need a polished brand deck to start. A rough sketch, a product photo, and the internal dimensions are enough to get the conversation moving. If you can tell us the product weight, like 180 g or 420 g, that helps too. Weight changes the board choice faster than people expect.
Pricing, MOQ, and What Wholesale Really Means
Let’s talk money. Custom window box packaging wholesale pricing drops as volume increases, but it does not fall in a straight line, and anyone who says otherwise is selling fairy dust. Tooling, print complexity, window film, board type, and finish selection all move the number. A clean one-color kraft box with a small clear window is a different animal from a full-color retail carton with foil, embossing, and a custom insert. A $0.15 per unit price for 5,000 pieces is possible on a basic run in Shenzhen, but only if the structure is simple and the artwork does not try to start a fight.
For practical context, I’ve seen simple custom window box packaging wholesale jobs land around $0.18 to $0.32 per unit at 5,000 pieces for basic paperboard, depending on size and structure. Add a clear PET window, and you may be looking at another $0.03 to $0.08. Add spot UV or foil, and the number climbs again. If you’re asking for premium rigid-style folding structures, you are no longer in “cheap box” territory. That’s just math. On a 10,000-piece order in Guangzhou, a 350gsm SBS carton with a small window and one-color print may land around $0.16 to $0.22 per unit, while the same box with foil stamping can move to $0.27 or higher.
MOQ, or minimum order quantity, depends on the production setup. Some factories will quote 1,000 units, but the unit price will make your eyes narrow. In many wholesale programs, 3,000 to 5,000 pieces is where custom window box packaging wholesale starts to make manufacturing sense. Lower quantities are possible, especially for startup trials or seasonal launches, but setup costs get spread across fewer boxes. That means the per-unit price rises. Not because someone is being difficult. Because machines and dies do not care about your launch calendar. A factory in Shenzhen might accept 500 pieces for a rush sample run, but that is a trial order, not real wholesale economics.
Sample costs usually range from a modest pre-production proof charge to a more expensive hard sample if you need exact board, film, and print replication. Die charges and plate charges can also appear. For a custom die-cut window, you may see a one-time die cost depending on complexity. A standard steel rule die is often far cheaper than a custom rigid-form die with many internal cut lines. If you’re buying custom window box packaging wholesale, ask whether tooling is one-time or reusable, and whether it’s included in the quote or separated out. People who skip this question always act surprised later. Every. Single. Time. A basic die can cost $80 to $180; a more intricate multi-window die can run $220 to $450 depending on the factory in Dongguan or Ningbo.
Here’s the blunt comparison I give clients:
- Stock box + label: lower setup, but limited presentation and weaker package branding
- Custom printed boxes without a window: better branding, less visibility
- custom window box packaging wholesale: more upfront planning, stronger shelf appeal, better product visibility
If your product sells on appearance, scent, color, texture, or gift appeal, custom window box packaging wholesale usually earns its place. If the product is purely functional and sold in a channel where presentation does not matter, a simpler carton may be enough. I’m not here to sell you more packaging than you need. That’s how you end up with expensive mistakes and warehouse regret. A $0.05 packaging upgrade on a $40 retail product may be smart; the same upgrade on a $6 item might be a vanity project.
Wholesale really means efficiency. It means the supplier is set up to quote larger runs with better material purchasing, faster die-cutting, and less labor per unit. It also means you should expect cleaner communication around lead times, QC, and reorder consistency. If a seller cannot explain how the pricing breaks down across 3,000, 5,000, and 10,000 units, they are probably guessing. I do not recommend paying for guesses. A good factory in Guangdong will tell you exactly how much the window film, board grade, and finish contribute to the final unit price.
Process and Timeline: From Quote to Delivery
The production flow for custom window box packaging wholesale should be straightforward, even if the details are not. First comes inquiry. Then spec review. Then quote. Then dieline confirmation. Then artwork proofing. Then sampling. Then approval. Then production. Then QC. Then shipment. That is the road map. If any supplier tries to skip three of those steps, they are either overconfident or underprepared. A clean project in Suzhou can move from initial quote to finished cartons in about three weeks if every decision lands on time.
In my experience, the biggest delay is not the press. It is the back-and-forth on specs and artwork. I once worked with a snack brand that needed custom window box packaging wholesale for a seasonal release. They sent beautiful artwork files and forgot to confirm the box orientation. The top panel and window alignment were off by a few millimeters on the first proof. Fixing it took one day. Waiting for approvals took four. That’s the real bottleneck. The art team in New York wanted one more revision, while the factory in Dongguan was already waiting on a yes-or-no answer.
Typical sample production can take around 5 to 10 business days, depending on structure and finish. Full manufacturing may take about 12 to 15 business days after proof approval for straightforward orders, but specialty coatings, large quantities, or complex inserts can add time. For custom window box packaging wholesale, shipping time is separate. Domestic delivery can be quick if inventory and freight are local. Overseas fulfillment may need additional transit, customs, and port handling time. If you’ve ever seen a container sit still for no good reason, you know why I separate production from shipping in every quote. From Shenzhen to Los Angeles, the ocean leg alone can add 18 to 28 days depending on the carrier and port schedule.
Proofing checkpoints are worth respecting. A digital proof confirms layout, placement, and copy. A physical sample confirms board behavior, window alignment, and structure. If you approve quickly and the artwork is ready, you can often save several days. If your team needs “one more internal review” from five different people, your schedule will drift. That is not a supplier problem. That is a committee problem. A digital proof in 24 to 48 hours is normal; a hard sample may take 5 to 7 business days if the dieline is already locked.
Custom window box packaging wholesale also needs a realistic shipping plan. Flat-packed boxes ship more efficiently than pre-assembled ones. If the product is being fulfilled from a warehouse with limited labor, flat-packed cartons can be a smarter choice. If you need retail-ready assembly, pre-glued or pre-formed packaging may be worth the added freight cost. I usually ask buyers to compare unit cost, freight cost, and labor cost together. Otherwise they make a false “cheap” decision and pay for it later in warehouse time. A pre-assembled carton can save 20 seconds per unit at the packing table, which matters a lot if your warehouse is in Dallas and your labor is $18 an hour.
For quality control, I like to see checks on print registration, window placement, glue strength, score accuracy, and carton squareness. If the box will go through retail distribution, testing against common handling standards matters. Organizations like ISTA provide packaging transit testing standards that help assess shipping performance, which you can review at ista.org. That matters more than people think, especially when you’re shipping fragile product or high-value retail packaging. A box that survives a drop test in Shenzhen usually behaves better in a fulfillment center in Ohio.
And yes, the classic “we needed it yesterday” panic still happens. Clean files, confirmed dimensions, and fast approvals are the antidote. For custom window box packaging wholesale, I’d rather see a buyer send one well-prepared request than five rushed emails with missing information and a deadline written in all caps. The first one gets a quote. The second one gets sympathy and a headache.
Why Choose Us for Custom Window Box Packaging Wholesale
I’ve spent 12 years in custom printing, and I’ve walked enough factory floors to know the difference between a packaging vendor and an actual manufacturing partner. We focus on custom window box packaging wholesale with real production discipline, not spreadsheet optimism. That means material sourcing, dieline support, print consistency, and QC checks that happen before cartons leave the floor. We work with production teams in Shenzhen, Dongguan, and Guangzhou because that’s where the tooling, presses, and finishing lines are already set up for this kind of work.
One thing I’ve learned from supplier negotiations: the cheapest paper quote is rarely the cheapest finished box. I once sat with a mill rep over a board order and watched a buyer try to save $0.02 per unit by switching to a thinner stock. Fine, except the finished cartons bowed under stack pressure and failed retail presentation. We moved back to the better board, trimmed one finish, and saved the project from looking like a budget accident. That’s the kind of decision-making that matters in custom window box packaging wholesale. A 320gsm stock can be fine for light soap, but a 350gsm C1S artboard often holds its shape better once the window is cut and the carton is stacked in a case pack of 24.
We help with packaging design decisions before production starts. If a box needs a different board grade, a smaller window, a changed insert height, or a more efficient print setup, we say it. No drama. No fake certainty. Just the kind of practical advice that keeps a project from turning into an expensive correction order. For buyers comparing Wholesale Programs, that support is a real advantage because it reduces waste and protects margin. If a 6 mm insert adjustment saves a reprint, I will say so before anyone signs off on a bad dieline.
Repeatability matters too. If your first run of custom window box packaging wholesale uses a precise PMS match and the next run drifts off color, your package branding weakens immediately. I’ve seen brands lose shelf consistency because their supplier treated color as “close enough.” That does not work for serious retail packaging. We use structured proofing and production checks so reorders stay aligned with the original approved sample. A delta E shift that looks tiny on a monitor can look huge under store lighting in Chicago or Toronto.
We also keep communication practical. If a finish adds $0.06 and only lifts perceived value by a small amount, I’ll say so. If a clearer window or a better insert will improve sell-through enough to justify the cost, I’ll say that too. That honesty is what buyers should expect from custom window box packaging wholesale. You are not paying for applause. You are paying for boxes that arrive right and work on shelf. A simple quote sheet with line items for board, print, film, and packaging labor is better than a glossy sales pitch with no numbers.
Buyers care about a few simple things: responsiveness, consistency, accurate pricing, and retail-ready packaging. That is the standard. Not fancy language. Not claims that sound impressive but collapse under a freight label. Just solid production, predictable communication, and packaging that does what it was designed to do. If a supplier can tell you the difference between a 12pt folding carton and a 350gsm artboard run without fumbling, you are probably talking to the right plant.
Next Steps: How to Get an Accurate Quote Fast
If you want a fast, accurate quote for custom window box packaging wholesale, send the basics first. Product dimensions. Box style. Quantity. Material preference. Print requirements. Deadline. If you already know the retail channel, include that too. A box for a boutique gift shop is not the same as a box destined for club distribution or bakery counters. The retailer in Austin wants different shelf impact than the warehouse club in New Jersey.
If you do not have a dieline, send a rough sketch or a reference photo with measurements. That is enough to start. I’ve had buyers send a phone photo with a ruler beside the product, and honestly, that was more useful than a ten-page brand deck with no dimensions. For custom window box packaging wholesale, the best projects start with clear physical specs, not marketing fluff. A photo taken on a kitchen counter in San Jose with the actual product and a tape measure is worth more than three rounds of “creative direction.”
Choose between a budget version and a premium version based on your retail price and sales channel. If your item sells for $12, the packaging should not behave like a $5 luxury rigid case unless the margin supports it. If your item sells for $40 and the box is part of the unboxing experience, then the premium path may be justified. That is the real packaging design conversation. No mystery. Just economics. A $0.24 carton may be plenty for a body bar; a $0.68 carton with foil, insert, and window film may be justified for a holiday gift set sold in London or Sydney.
I recommend asking for two quote options side by side. One with the lean structure. One with the upgraded finish. That makes it easier to compare unit cost versus shelf impact. For custom window box packaging wholesale, this kind of comparison keeps teams from making emotional decisions disguised as branding decisions. I have seen enough of that to be mildly suspicious of any meeting that starts with “Let’s just make it look nicer.” Nicer compared to what? And at what cost? A clear comparison usually shows whether the upgrade adds $0.04 or $0.14 per unit, and that changes the whole conversation.
Here’s the simple action plan I give every buyer:
- Confirm product size and shape
- Pick the box structure and window style
- Request two pricing tiers
- Review the dieline and proof
- Approve a sample before mass production
- Lock the production schedule and shipping method
Do that, and custom window box packaging wholesale becomes manageable instead of chaotic. Skip it, and you get expensive surprises with a tracking number. The difference between a clean 12- to 15-business-day production window and a three-week mess is usually one missing measurement.
Custom Logo Things is built for buyers who want real answers, not packaging theory. If you need custom window box packaging wholesale, start with a clean spec sheet and a realistic quantity target. Then we can help you choose the right board, window, finish, and production path without wasting a week on guesswork. That is how good packaging work gets done. If your target is 5,000 pieces in Shenzhen or 10,000 pieces in Dongguan, send the details and we can quote the actual job instead of the fantasy version.
FAQs
What is the minimum order for custom window box packaging wholesale?
custom window box packaging wholesale MOQ depends on the box style, paper stock, window type, and print complexity, but wholesale custom orders usually start at a production-efficient quantity rather than a one-off retail run. Lower MOQs are possible, but unit pricing rises because setup and die-cut costs are spread across fewer boxes. A 3,000-piece run is often more practical than 500 pieces if you care about real wholesale pricing. In many factories around Shenzhen and Dongguan, 5,000 pieces is the point where pricing starts to feel like wholesale instead of a sample order with a fancy label.
Can I get custom window box packaging wholesale with a clear film window?
Yes. PET or a similar clear film is commonly used when you want product visibility and added protection. For custom window box packaging wholesale, the best film choice depends on the product, shelf life, and whether the box will be used for food, cosmetics, or non-food retail items. If the product needs a barrier against dust or grease, film is usually the better move. A 0.2 mm PET window is common for retail cartons made in Guangzhou and Suzhou because it balances clarity, cost, and handling strength.
How long does wholesale custom window box packaging take to produce?
The timeline usually includes proofing, sampling, production, and shipping, so the total depends on approval speed and order size. For custom window box packaging wholesale, fast approvals and ready artwork can shorten the schedule significantly. Missing details, unclear specs, and late changes always slow things down. That part never gets old, unfortunately. Once proof approval is locked, straightforward production is typically 12 to 15 business days, and sample making is often 5 to 10 business days depending on structure and finish.
What affects the price of custom window box packaging wholesale the most?
The biggest price drivers are quantity, material grade, box structure, window style, finishing, and insert requirements. custom window box packaging wholesale also gets more expensive with rush production, specialty coatings, foil stamping, spot UV, and complex die cuts. If someone quotes a low number without asking about these items, be careful. They may not be quoting the real job. A 350gsm C1S artboard box with a small PET window can be very affordable, but a rigid-style foldable carton with foil and embossing in one of the Guangzhou plants will land in a different budget bracket.
What files do I need to order custom window box packaging wholesale?
You should send product dimensions, box style preference, quantity, artwork files, and any print or finish requirements. For custom window box packaging wholesale, if you do not have a dieline, a manufacturer can usually provide one after reviewing your product size and structure needs. A rough sketch and a clear photo are enough to start if you are still early in the process. If you can include the target quantity, such as 3,000 or 10,000 units, the quote will be much closer to reality from the start.
How do I decide whether to use a window at all?
Use a window when the product sells better through visibility, texture, color, or gift appeal. For custom window box packaging wholesale, that usually means candles, soaps, baked goods, accessories, and premium sets. Skip the window if the product needs more privacy, more protection, or a fully printed surface for storytelling. A window is not mandatory. It is a selling tool. If it does not improve retail performance, save the money and keep the carton simpler.
