Custom clothing mailer boxes work well when the package is part of the customer experience. The box should fit the folded garment without adding too much empty space.

Mailer box checks
| Detail | Watch point |
|---|---|
| Folded garment size | Controls box size and carton packing |
| Inside print | Good for DTC unboxing without extra inserts |
| Care card | Should fit without bending |
| Board strength | Match product weight and shipping route |
| Carton size | Repeated orders make volume important |
For first orders, keep the mailer structure simple and test print, fit and packing speed before scaling.
