Custom subscription boxes for repeat branded programs.
Plan a custom ear-lock corrugated subscription box for recurring assortments, membership programs, and repeat product deliveries. UPG manufactures the approved structure with exterior or interior branding and custom insert options.

What buyers should know first.
A custom subscription box is a branded ear-lock corrugated mailer planned for a recurring program. The structure should reflect the typical product range, intended presentation, quantity, and delivery requirements, with any changing assortment reviewed before final specifications are approved.
Where subscription boxes fit best.
Start with the campaign or program goal, then develop the mailer around the products, presentation, quantity, and destination.
Recurring product assortments
Membership and discovery programs
Seasonal subscription collections
Repeat branded unboxing programs
Shape the brief before the artwork.
A clear product and presentation plan helps the structure, insert, and artwork move in the same direction.
Define the typical assortment
Use representative product dimensions and the expected item count to establish the starting structure and insert plan.
Plan for repeatable presentation
Keep artwork zones and product organization clear enough to support the approved recurring program.
Review meaningful changes
A changing product mix can affect fit and presentation, so new assortments should be checked against the approved structure.
Coordinate the box, print, and product arrangement.
These options are reviewed against the approved ear-lock structure, project quantity, and presentation goal.
What to send for a useful first review.
You do not need a finished specification to start. Share the facts and files already available, and UPG will review the next structural and commercial steps.
