Kraft mailing boxes are built for one job — getting a product from warehouse to doorstep securely, quickly, and on-brand. Our custom kraft mailing boxes feature a self-locking tuck closure that needs no tape for standard use, along with an optional tamper-evident seal strip for added security.

Constructed on kraft corrugated or heavyweight kraft folding board depending on product weight, mailing boxes can be printed with a brand logo, interior messaging, and return instructions in spot-colour flexo or full-colour with white underprint.

A staple for DTC and e-commerce brands shipping directly to consumers at volume.
