Custom Mailer Boxes are self-contained cartons built for the ecommerce journey, from single orders to subscription runs. The folding structure locks together without loose lids or extra parts, so packing is quick and the box arrives with a clean, printable exterior.

Made to your custom size, the internal footprint can be matched to your product so it does not slide during transit. A snug fit protects the item and shapes the moment of opening, which for subscription and gifting brands is part of what the box is for. Telling us whether the box is a one-off order or part of a repeating subscription also helps, since that can influence how much interior branding is worthwhile.

Shaping the unboxing

Inside print and a fitted insert turn a plain despatch box into a considered reveal. Decide how much of the interior you want to brand and whether the product needs holding in place, then check the effect on a sample before a full run.

Specification points

  • Corrugated construction for transit protection
  • Self-locking structure for fast packing
  • Custom internal size and optional fitted insert
  • Inside and outside print for the unboxing

Minimum order is 100 units. Send your product dimensions and any insert needs, tell us how much of the interior you want to brand, and we will quote the mailer, insert and inside-and-outside print for the unboxing.
