13 x 13 x 3" Kraft Deluxe Literature Mailers

These 13 x 13 x 3 inch kraft literature mailers are built from ECT-32-B corrugated board and feature a tab-locking tuck closure that assembles without tape, glue, or staples — cutting packing time and eliminating the need for additional sealing materials. Protective side flaps reinforce sidewall stability and help secure contents throughout transit.

The square footprint and 3" depth make these mailers a practical fit for catalogs, marketing collateral, folded documents, framed artwork, hard goods, and product samples. E-commerce fulfillment centers, print distributors, retail supply chains, and corporate shipping departments all benefit from the consistent geometry and self-contained closure.

Constructed from kraft corrugated with a B-flute profile, these mailers deliver rigid protection without requiring box tape or a separate sealing step. They are sold in bundles of 50 and ship via parcel carrier.
