How to Design Subscription Box Packaging That Sells

If you want to know how to design subscription box packaging that actually sells, start with this uncomfortable truth: the product inside is not always the first thing people remember. I watched a skincare brand lose repeat orders because their inserts looked cheap, even though the serum was excellent and the box itself cost them $1.84 per unit at 10,000 pieces. Customers posted the unboxing, not the formula. That stung, but it paid for a better design the second round. We switched to a 350gsm C1S artboard insert with a matte aqueous coating, and the return complaints dropped enough to justify the extra $0.12 per unit.

I’ve spent 12 years in custom printing, and I’ve seen the same mistake over and over. Brands treat subscription packaging like a decorative afterthought, then wonder why churn climbs or fulfillment turns into a mess. How to design subscription box packaging is not just about colors and logos. It’s structure, protection, pack-out speed, freight math, and customer psychology all packed into one rectangle. I’ve stood on factory floors in Dongguan and Ningbo while a client argued over 3 mm of headspace like it was a philosophical debate. It wasn’t. It was the difference between a clean fit and a crushed candle.

The good news? You can absolutely build a box that looks premium, ships safely, and keeps margins intact. You just need to design it like a packaging system, not a pretty sleeve with delusions of grandeur. Honestly, that “we’ll figure it out later” attitude is how you end up paying for reprints and apologizing to customers on a Friday night. A better plan is to lock your size, board spec, and print method before anyone starts picking hex codes.

What Makes Subscription Box Design Work

On a factory floor in Shenzhen, I once watched a team spend 40 minutes debating a 2 mm flap adjustment on a mailer box. Sounds dramatic. It was. But that tiny change cut product movement by about 18% during a drop test and saved the client nearly $0.09 per return-avoidance unit over time. That is the kind of detail that separates good packaging from expensive cardboard theater. If you’re learning how to design subscription box packaging, that’s the mindset you need. I’ve seen the same result in Ho Chi Minh City, where a 1/8-inch insert tweak turned a rattly beauty box into one that survived a 24-inch corner drop with no product damage.

Subscription box design is a blend of branding, structural packaging, shipping protection, and a repeatable unboxing experience. Retail packaging fights for attention on a shelf. Subscription packaging wins attention at the doorstep and in the customer’s hands. That changes the rules. You’re not just asking, “Does this look nice?” You’re asking, “Will this feel exciting the same way on box 1,000 as it did on sample one?” In one project I handled for a tea brand in Portland, Oregon, we tested three lid opens and found that the version with a 15 mm thumb notch got a 27% faster first reveal in user testing. Tiny detail. Big effect.

Here’s what most people get wrong: they think the box has to do everything. It doesn’t. A strong design guides the eye, protects the product, and makes the customer feel like the brand planned the whole experience with intention. That could mean a simple kraft mailer with one-color print, or a full-color SBS board with a matte aqueous coating and a spot UV logo. The best answer depends on the product, price point, and fulfillment model. For a coffee subscription shipping from Los Angeles, California, a 32 ECT corrugated mailer with a single-color exterior print can beat a fancy rigid box if the target is under $2.00 landed packaging cost.

Retail packaging wins on the shelf because shoppers compare it against neighboring brands in three seconds. Subscription packaging wins because it arrives as a surprise. That surprise creates a tiny emotional spike, and that spike is what gets posted on Instagram, TikTok, or a friend’s group chat. I’ve seen brands spend $0.30 on a custom insert and generate more user-generated content than a $4.00 premium rigid box with no reveal moment. Funny how that works. In one case out of Melbourne, a $0.18 sticker seal created more shares than a foil-stamped lid that cost $2.70 per unit.

The core goal of how to design subscription box packaging is simple: make it look good, ship safely, and stay profitable at scale. If one of those three breaks, the whole thing becomes annoying fast. And annoying packaging is usually expensive packaging in disguise. If your box takes 95 seconds to pack instead of 45, that extra 50 seconds can add thousands of dollars in labor over a 10,000-box month. You feel that in the warehouse. You also feel it in the profit statement.

Client quote I still remember: “We want premium, but we also want to keep our pack-out under 90 seconds per box.” That’s a real brief. And it’s a sane one. Their final spec was a 24-point SBS tray inside a corrugated shipper, packed in 78 seconds on average in Austin, Texas.

For standards and testing, I always point brands to the basics: ISTA for transit testing, EPA for materials and waste reduction guidance, and FSC if you want responsibly sourced paperboard. Standards are not glamorous. They do, however, save money and headaches. A 24-inch drop test and a simple compression check can keep you from discovering a broken jar after 4,000 units have already shipped.

How Subscription Box Packaging Works From Concept to Delivery

If you’re figuring out how to design subscription box packaging, the process matters as much as the artwork. I’ve seen founders skip straight to design comps and then discover the box can’t fit the product, the insert adds 12 seconds of pack time, or the carrier surcharges blow up the budget. That’s not a design failure. That’s a process failure. One brand I worked with in Chicago had a beautiful mockup that looked great in Photoshop and failed immediately once we loaded three 6-oz glass jars into it. The inside cavity was 4 mm too tight. That 4 mm became a six-week delay.

Here’s the workflow I use with brands that want fewer surprises. First comes concept. You define the size, experience, and budget. Then comes the dieline, which is the flat template showing fold lines, glue areas, and bleed. After that, you create a sample, test the fit, and check the finish. Once the structure is approved, you move into production, then fulfillment, then delivery to the customer. Simple on paper. Messy in real life. A standard sample cycle usually takes 5 to 7 business days if the supplier already has a stock board like 350gsm C1S artboard or 32 ECT corrugated on hand.

The packaging system usually includes four parts: the outer mailer or shipper, the inner product packaging, the insert or divider, and the seal or closure. I’ve worked on beauty boxes where the outer mailer was a plain 32 ECT corrugated shipper, but the inside had a printed SBS tray, tissue wrap, and a branded sticker seal. That combination looked high-end while keeping the shipping carton inexpensive. Smart. Not flashy for the sake of flashy. We quoted one version at $0.78 per unit for 5,000 pieces in Guangzhou, then saved another $0.04 by switching the insert from foam to die-cut paperboard.

Common formats include mailer boxes, rigid boxes, corrugated shippers, sleeves, and tissue wraps. Mailer boxes are the easiest starting point for most brands because they’re strong, mail-friendly, and relatively cheap to print. Rigid boxes feel premium, but they often need more hand assembly and more storage space. Corrugated shippers win on protection. Sleeves and wraps add visual polish without major structural complexity. There’s no universal winner. There’s only the right answer for your pack-out and ship method. A cosmetics brand in Toronto may need a 16-ounce shipper with dividers, while a sock subscription in Nashville may only need a one-color kraft mailer and a tissue insert.

Fulfillment constraints shape the box more than founders expect. If your team packs 500 orders a day, adding a 6-piece insert system can turn a nice concept into a bottleneck. I’ve stood on packing lines in Los Angeles where a 15-second increase per box meant two extra staff members on payroll, which translated to roughly $3,600 a month in labor. That’s not theoretical. That’s an invoice. I’ve also seen a warehouse in Jersey City reject a box because the tuck flap opened too easily when stacked 12-high on a conveyor.

Design and logistics teams clash because they measure success differently. Designers care about mood, hierarchy, and visual story. Operations cares about fit, speed, and damage rate. Both are right. The trick is to involve both early, before anyone commits to a structure that looks beautiful and packs like a punishment. If your supplier is in Shenzhen, Yiwu, or Dongguan, send them the final product dimensions in millimeters, not “about wallet-sized.” The factory will not interpret vibes.

When you’re learning how to design subscription box packaging, think in systems. A pretty box that arrives crushed is a refund. A tough box that feels boring is a missed marketing opportunity. Balance both. One of the best-performing boxes I ever helped develop was a simple white mailer with a one-color navy print, a 1.5-inch reveal on the inside lid, and a recycled paper insert. It cost $1.03 per unit at 10,000 pieces and looked far more expensive than it was.

Key Factors to Consider Before You Design

Before you even open Illustrator, gather the facts. I mean actual facts: product dimensions, unit weight, shipping method, monthly volume, and whether the customer is meant to reuse the box. One client once insisted on a “luxury” box, then admitted their product was 3.8 ounces and shipped in a poly mailer to keep costs down. That mismatch cost them two redesign rounds and about $1,200 in sample fees. Avoid that kind of comedy. A 9 x 6 x 2-inch product packed for USPS Ground Advantage needs a different structure than a 14 x 10 x 4-inch skincare set going out via UPS from Atlanta.

Your brand identity matters, obviously. But not in a vague “make it pop” way. You need a clear color palette, typography system, logo placement rules, and a point of view on the unboxing story. Are you playful? Clinical? Gift-like? Minimal? I’ve seen subscription brands use the same PMS colors on the box, insert, and tissue wrap, then wonder why the result feels flat. The answer is usually contrast and hierarchy, not more decoration. A matte black exterior with a single silver foil mark can feel more premium than a full rainbow print if the product is positioned at $39 to $79 per month.

Product dimensions and fragility come next. If you’re packing glass vials, supplements, candles, or ceramics, you need to know exactly how much movement is acceptable. Sometimes a 1/8-inch insert change eliminates rattle. Sometimes you need chipboard dividers or molded pulp trays. If the product can’t survive a 24-inch drop, don’t design like it can. Standards from ISTA testing exist for a reason. I’ve had a candle brand in Phoenix pass after moving from a loose kraft filler setup to a die-cut tray with 3 mm tighter cavities.

Substrate and finish choices matter more than most people realize. For cartons, you’ll typically choose between corrugated board, SBS, CCNB, or rigid chipboard wrapped in printed paper. Finishes include matte aqueous, gloss aqueous, soft-touch lamination, spot UV, foil stamping, embossing, and varnish. I’ve priced mailer boxes at $0.52/unit for a 5,000-piece run with one-color print and no finish, and I’ve also seen fully printed rigid boxes run $4.20/unit before inserts. Same product category. Very different margins. A 350gsm C1S artboard with matte lamination in Suzhou is not the same budget story as a magnet-closing rigid set in Dongguan.

Now the money part. Setup costs, print method, minimum order quantities, and unit pricing all change the shape of how to design subscription box packaging. Digital printing can be flexible for lower runs, but litho or flexo may become more economical at scale. A custom dieline may be included, or it may cost $150 to $500 depending on the supplier. Tooling for specialty structures can add another $300 to $1,500. No one loves that line item, but there it is. If you ask for foil, embossing, and a custom insert on a 1,000-unit run, expect the setup to sting a little.

Sustainability is not just a marketing checkbox anymore. Recycled content, right-sizing, and fewer components can cut freight and waste. I’ve seen brands move from a 14-inch box with excess void fill to a 10-inch right-sized mailer and reduce dimensional weight charges by 11% on average. Less cardboard, less air, less money. The planet likes it too, which is nice. A 32 ECT corrugated mailer made in Wisconsin can outperform a heavier imported rigid box if the goal is lower emissions and faster replenishment.

If you want to make how to design subscription box decisions with fewer surprises, write down your constraints first. Brand feel. Product safety. Labor limits. Cost ceiling. Then build from there. It’s much cheaper than falling in love with a box your fulfillment team hates. And trust me, if the warehouse team hates it, they will absolutely let you know. Usually with a tape gun in one hand and a very deadpan expression in the other.

Step-by-Step: How to Design a Subscription Box

Good how to design subscription box work starts with the customer experience map. I ask brands to think through five moments: opening, discovering, using, storing, and reusing. What happens when the tape is cut? What does the customer see first? Is the hero product visible, or buried under filler? Can the box be kept on a shelf, or is it going straight into recycling? Each decision changes the structure and the art. If you’re selling in the U.K. or Canada, the reuse question matters even more because customers often keep the outer carton for storage.

Step one is choosing the box structure. For most subscription programs, a mailer box is the cleanest starting point. If the brand is premium and the box is a major part of the experience, a rigid box may work better. If the product is heavy or fragile, a corrugated shipper with internal inserts might be the safest option. I’ve seen a candle subscription use a 32 ECT corrugated mailer with kraft paper crinkle and die-cut inserts, and it performed better than the fancy rigid sample that cost three times as much. That sample came in at $3.66 per unit from a supplier in Shenzhen, which looked great until the warehouse team had to hand-fold every unit.

Step two is building the visual layout. You need a logo, a pattern or supporting graphic, short messaging, and a clear hierarchy for the inside of the box. The outside should create anticipation. The inside should reward it. That’s where many brands waste space by printing every inch. Don’t do that unless your brand truly needs it. Empty space with intention often feels more premium than clutter. One brand I worked with in Denver used a 2-color exterior and a full-color inside lid, and the contrast made the product feel more expensive than a fully printed exterior ever would.

Step three is creating or requesting the dieline. This is where expensive mistakes happen if the file is handled casually. Keep artwork inside bleed margins, respect glue zones, and do not place critical text across folds. I once had a client send a beautiful full-wrap design with their tagline dead center on a panel fold. The printed sample looked like the line between two arguments. We fixed it, but the proof delay added six days. A good factory in Dongguan will usually turn a dieline within 24 to 48 hours if the dimensions are final and the board spec is known.

Step four is sample approval. This is not optional if you care about results. Request a physical sample, check the board thickness, inspect the print color, and load the product. If possible, do a basic transit test with real contents. Drop it from 24 inches on corners and edges. Shake it. Stack it under a few other boxes. You don’t need a lab to catch obvious problems, though a certified test from an ISTA-aligned facility is better when volumes are high. A sample approval cycle typically takes 3 to 5 business days once the sample is in hand, assuming nobody discovers the logo is upside down.

Step five is refining the design before production. Small changes now are cheap. Changes after print plates are made are not. I’ve seen a brand pay an extra $780 because they changed a foil placement after final approval. That money could have covered better inserts or a freight upgrade. A better move is to lock the final artwork after one physical review, not after the third “tiny tweak” that somehow requires a new proof in Guangzhou.

Step six is coordinating supplier, printer, and fulfillment. This is where the email chaos begins if no one owns the timeline. Use one file with dimensions, materials, quantities, and approval dates. Make sure your supplier knows the pack-out sequence. If the team inserting products needs the box to stay open by itself, say that. If the box must fit in a master carton of 24 units, say that too. Precision saves meetings. Precision also saves expensive shipping mistakes, like the time a 12 x 8 x 3 box was quoted, approved, and then discovered not to fit the retailer’s 15-inch shelf display.

Here’s the short version of how to design subscription box packaging without chaos:

1. Map the customer journey.
2. Pick the right structure.
3. Build the artwork around the dieline.
4. Approve a physical sample.
5. Test shipping durability.
6. Lock the pack-out and production timeline.

That process sounds basic because it is. The hard part is sticking to it when someone wants to “just make it a little fancier.” That little bit is usually where budgets go to die. I’ve watched a “small tweak” turn into a two-week delay more times than I care to admit. One soft-touch finish request added $0.22 per unit and pushed a ship date from March 14 to March 28 because the coating line in Shenzhen was booked.

Subscription Box Cost and Pricing Breakdown

Budgeting is where how to design subscription box projects either stay sane or become a cautionary tale. The biggest cost drivers are box style, board thickness, print coverage, finish, inserts, and quantity. A simple one-color mailer on E-flute corrugated board will cost far less than a fully printed rigid box with foil, soft-touch lamination, and custom foam. Shocking, I know. Fancy things cost money. If your box ships from Shenzhen to Long Beach, the freight line item can be as important as the print quote.

Here’s a rough framework from projects I’ve handled. A basic corrugated mailer might land around $0.45 to $0.90 per unit at 5,000 to 10,000 units, depending on size and print coverage. A more premium mailer with full color and coating can climb into the $1.10 to $2.00 range. A rigid subscription box with wrapped chipboard, magnets, or specialty finishes may start around $2.50 and go well past $5.00, especially if there are inserts or hand assembly steps. For example, I quoted a 12 x 9 x 3-inch mailer at $0.68 per unit in Qingdao, then the same structure with a full inside print and spot UV came back at $1.14 per unit.

Hidden costs are where many brands get surprised. Tooling for a custom structure can add a few hundred dollars. Freight from Asia can swing wildly depending on carton volume and season. Storage fees pile up if you order 20,000 boxes but only ship 3,000 a month. Assembly labor matters too. If each box takes 20 extra seconds to pack and your warehouse handles 8,000 units monthly, that can turn into real payroll. A fulfillment center in Las Vegas once told me a 15-second increase on a 9,000-box run added nearly 38 labor hours a month. That is not a rounding error.

There’s also the cost of damage replacements. A poorly designed box may look cheaper on paper, but if the breakage rate rises from 1% to 4%, you’ve just created a new expense category. I’ve sat in meetings with brands where the box itself was $0.14 cheaper, but the damage claims were $2,800 a month. That math does not impress investors. Neither does sending replacement candles from Nashville because the insert was off by 5 mm.

Ordering larger volumes lowers unit cost. That part is true. But it also ties up cash in inventory. If you’re a smaller brand, a 25,000-unit order may look attractive on the quote sheet and terrible in the bank account. This is why learning how to design subscription box packaging includes learning how to forecast. A low unit price is not the same as a low total cost. If your monthly shipment volume is 2,000 boxes, a 10,000-unit order can sit in a warehouse in Ohio for five months before it pays for itself.

My practical budgeting advice: set your packaging target as a percentage of your selling price and your gross margin. For many subscription brands, packaging needs to stay somewhere around 8% to 15% of the first-month revenue depending on the category and retention goals. That is not a law. It depends on whether you sell beauty, food, apparel, collectibles, or premium gifts. But it’s a useful starting point, and better than guessing. If your box costs $1.26 on a $24 monthly subscription, you’re probably in range. If it hits $3.90, you need a very good reason.

Common Subscription Box Design Mistakes to Avoid

The worst mistake I see in how to design subscription box projects is making something beautiful that fails in shipping. I’ve seen gorgeous rigid boxes crushed because the board spec was too light for the product weight. I’ve also seen mailers so oversized that the inserts had to work overtime to stop movement. If the product bounces, the customer notices. Then they email support. Then you pay twice. One cosmetics brand in San Diego had a 2.8 lb box built on a 16 ECT shipper. It looked nice until the corners collapsed.

Another common problem is ignoring the insert strategy. If the items rattle around, the unboxing feels cheap and the product may arrive damaged. Inserts do not have to be expensive, but they do have to fit. A die-cut paperboard insert can be enough for light products. Heavier items may need corrugated dividers, molded pulp, or EPE foam. The right answer depends on product fragility and what the carrier will do to the box between pickup and delivery. Spoiler: carriers are not gentle. A 6-ounce bottle in a 4 mm loose cavity will find the edge of the box every time.

Overbranding is another trap. A box with logos on every panel, five taglines, and three different fonts can feel noisy instead of premium. I know some founders think more ink means more value. It usually means less clarity. A strong brand can breathe. Negative space is not wasted space. It’s a design tool. I’ve seen a black mailer with one copper foil logo outperform a fully illustrated box because the premium signal was cleaner and the print cost was $0.33 lower.

Skipping sample approval is pure gambling. Color shifts happen. Board creases behave weirdly. A lid that looked fine in a PDF may pop open in real life. I had one client approve artwork without touching the physical sample, then discover the hot foil cracked along the fold when opened. Reprint cost: $1,140. A very educational mistake. The expensive kind. The same thing can happen with soft-touch lamination if the supplier in Zhejiang applies too much heat.

Underestimating pack-out speed can kill a good concept. If the packaging requires too many steps, your warehouse will hate it and your labor cost will balloon. I’ve watched a beautiful custom box get rejected by operations because the pack time hit 2 minutes and 10 seconds per unit. The team had a 45-second target. That gap mattered more than the logo placement. If a 10,000-box month is the plan, every extra 10 seconds becomes a very real line item.

To keep how to design subscription box work on track, test the full system, not just the artwork. Structure, insert, packing flow, shipping, and customer presentation all need to work together. One weak link and the whole thing feels cheap, even if the box cost a fortune. I always want to see the full pack-out in a real warehouse, with actual tape guns, actual labels, and actual people rushing because it’s 4:45 p.m.

Expert Tips for Better Unboxing, Lower Costs, and Faster Launches

If you want better unboxing without setting cash on fire, design for the camera. Seriously. One strong reveal moment beats decorating every surface like it owes you money. Put the visual energy where the customer opens the box and sees the hero product or message. That’s the photo zone. That’s where attention lives. A 1.25-inch message panel under the lid can do more than a full wrap if the customer only sees it for three seconds.

Use modular box sizes if your product line changes often. I worked with a snack brand that kept changing SKU counts each quarter. Instead of making a new box every time, we settled on two modular mailer sizes with different insert configurations. That cut tooling changes and reduced leftover inventory by about 22%. Boring strategy. Excellent result. The supplier in Yiwu charged $180 for each insert revision, which was far cheaper than inventing a brand-new carton every month.

Keep one area for seasonal or promotional messaging, while the core packaging stays consistent. That gives you flexibility without reprinting the entire system every month. A belly band, sticker, or insert card can do a lot of marketing work for a very small cost. I’ve seen a $0.06 sticker carry a Valentine’s campaign better than a full box redesign that cost the client $4,900 in creative and sampling. If you need to localize for Dallas one month and Miami the next, variable inserts are your friend.

Test real shipment routes. Not just a desk drop. Not just a cheerful little tap on the table. Ship the sample through the actual carrier path you’ll use. If your boxes travel from New Jersey to Texas in summer heat, or from California to Chicago in wet weather, that matters. Board can warp. Adhesives can soften. Ink can scuff. Real life is rude like that. I once had a sample sail through a local handoff and fail spectacularly after two days in a USPS network moving through Memphis in August.

Work backward from timeline. Sample approval, print production, transit, and fulfillment buffers all need room. For a straightforward mailer box, I’d usually allow 7 to 10 business days for sampling, 12 to 20 business days for production depending on quantity and finish, plus freight time. For more custom structures, add another round. Rushing packaging always costs more than planning it. In practical terms, a proof approved on Monday in Guangzhou usually means your finished boxes land around 12-15 business days later if the material is standard and the season is not peak.

One more point on how to design subscription box packaging: keep your supplier loop tight. Ask for a written quote, a dieline, a sample timeline, and a production schedule. If a vendor won’t spell out board spec, quantity, and lead time in writing, you’re not negotiating. You’re hoping. That’s not a strategy. I want to see exact numbers, like $0.15 per unit for 5,000 pieces on a plain one-color insert, or $0.42 per unit for a laminated mailer from Shenzhen, before I sign off on anything.

And yes, I’ve had suppliers try to “upgrade” materials without asking because they thought it sounded helpful. Helpful is fine. Unapproved is not. Always confirm spec changes, even if the rep says it’s “basically the same.” That phrase has cost brands more money than bad artwork ever did. A switch from 300gsm to 350gsm board changes stiffness, weight, freight, and sometimes the die-cut tolerance. “Basically the same” is how people get surprise invoices.

Your Next Steps to Design a Subscription Box That Works

If you’re ready to move from idea to execution, start with a clean audit. Measure your products. Note the shipping method. Set your target packaging budget. Decide whether the box is meant to feel practical, premium, playful, or collectible. Then collect reference images and brand assets in one folder. That gives you the foundation for how to design subscription box packaging without wandering around in circles. A clean brief with dimensions in millimeters and product weight in grams will save you from a lot of painful back-and-forth.

Next, write a packaging brief that includes product dimensions, quantity, order frequency, finish preferences, sustainability requirements, and pack-out instructions. The more specific you are, the fewer revision rounds you’ll need. I’ve seen briefs with six bullet points produce better quotes than vague decks with thirty slides and no measurements. Measurements win. Every time. If your order ships from Canada, note the province, carrier, and carton count per master case. That tiny detail can shave days off the quote cycle.

Then request a dieline and sample quotes from a packaging supplier. If you’re working with a manufacturer, ask for material options and price breaks at multiple volumes. I like to compare at least three quantities, such as 5,000, 10,000, and 25,000 units. That tells you where unit economics actually improve and where storage risk begins. It also shows whether a supplier in Dongguan can hit your target at scale or whether a local printer in California makes more sense for a faster launch.

Test one prototype with real products and a simulated shipment before you place the full order. Open it. Shake it. Ship it. See what happens. That one test can save you from a very costly lesson later. If the box survives and the unboxing feels right, lock the structure, artwork, and pack-out plan. Then move into production with a clear timeline and one person accountable for approvals. For a simple run, I’d expect sample approval to production handoff to take about 2 to 3 weeks if the supplier is in Guangzhou and the artwork is already final.

If you keep one thing in mind while learning how to design subscription box packaging, make it this: the best box is not the fanciest box. It is the box that protects the product, delights the customer, and fits the numbers. Fancy is easy. Functional is profitable. And functional is what keeps the lights on. I’ve seen a $0.89 mailer outperform a $6.10 rigid box because it got the specs right and the warehouse team actually liked packing it.

So here’s the actionable takeaway: define your product dimensions, choose the right structure, request a physical sample, and test it through the real fulfillment flow before you print a single large run. Do those four things in order, and you’ll save yourself a lot of money, time, and apologetic emails. Skip them, and the box will tell you exactly what went wrong. Usually by arriving crushed.
