Subscription Boxes.

Design one fixed exterior around your largest likely month, then take up the slack inside with an insert or fill. Our common formats are 9 × 6 × 3 in and 12 × 9 × 4 in, and most programmes settle on two or three sizes and pick one per month's mix. That keeps the die, the print and the packing routine stable.

Don't oversize by habit. Every spare inch is paid for in freight on every renewal, so right-sizing pays back far more here than on a one-off order.

Keep the box constant and let a printed sleeve carry the monthly or seasonal change. A new sleeve costs a fraction of a full redesign, and the structure, die and interior print stay the same run after run. Subscribers still get something new to photograph.

Brands that reprint the whole box every month usually end up with short runs of each design and a warehouse holding leftovers from months gone by.

Test a filled box to ISTA 6 or a comparable protocol before month one ships. A subscription box travels without an outer case, so it takes every drop and every stack load on its own. Designs that fail have usually been optimised for the unboxing photo and not for the sort.

Run the test with the heaviest month's contents and your actual carrier. Damaged deliveries early on are hard to win back from with a new subscriber.

E-flute is our standard, and we step up to B-flute when the monthly contents include glass or run heavy. E-flute prints cleanly and keeps the box slim for the mail. B-flute has taller flutes, so it cushions better and resists crushing under stacked parcels.

If only a few months carry heavy items, it can still pay to build the whole programme in B-flute so you aren't holding two box specs. The fluting we use carries high recycled content either way.

On a subscription box it earns its cost faster than on almost any other mailer, because the same interior print works every month a subscriber stays. You pay for it once in the artwork setup, and it shows up at every reveal. A flood colour inside with one short line of copy is plenty.

For the outside, matte lamination keeps glare down under the ring lights most unboxing videos are filmed with.

The insert holds each item in a set position, so the first thing seen when the lid opens is decided in advance. A die-cut paperboard insert can put the hero item in the middle with smaller pieces around it. It also stops everything sliding into one corner in transit.

If the mix changes monthly, a modular insert with a few standard cavities is more practical than cutting a new tool each month.

The floor is 500 boxes per design, and a programme can scale to 100,000 in a single order. Because the box itself stays constant, many programmes order one larger run and switch the monthly look with sleeves. That keeps the unit cost of the box down.

Hold a couple of months of boxes in stock, since a referral push or a press mention can bring a sudden jump in sign-ups.

Leave room for a sample and a transit test before bulk, then allow 7 to 10 business days for the production run. A launch sample lands with you 5 to 7 business days after it is ordered. If a launch date gets tight, rush production cuts the run to 5 to 7 business days.

Treat the sample as part of the launch plan. The fee is credited against the production order, and the box you test is the one you'll ship.
