13 x 13 x 3" White Deluxe Literature Mailers

These 13 x 13 x 3 inch white deluxe literature mailers are built from ECT-32-B single wall corrugated board and close securely without tape, glue, or staples. Front locking tabs engage the closure while protective side flaps reinforce the structure for stacking during transit and storage. The all-white exterior delivers a clean, professional presentation straight out of the bundle.

The 3" depth suits catalogs, flat-packed apparel, printed materials, framed artwork, and documents — making these mailers a practical fit for e-commerce fulfillment centers, print distributors, subscription box operations, and retail replenishment workflows. The square footprint handles square formats that standard rectangular mailers cannot accommodate efficiently.

Each mailer assembles in seconds with no additional tools or sealing materials, supporting fast pack-out at volume. Bundles of 50 ship via parcel carrier, allowing facilities to reorder in quantities that match their output without committing to large pallet volumes.
