These 13 x 13 x 4 inch white literature mailers are built from ECT-32-B single wall corrugated board, delivering rigid transit protection in a clean white finish suited for both branded and unbranded outbound shipments. The self-locking tab closure secures without tape or additional supplies, streamlining pack-out at the station.

The square footprint and 4" depth make these mailers a practical fit for catalogs, folded documents, sample packets, and similarly dimensioned flat goods. E-commerce fulfillment operations, print distributors, and B2B shippers regularly use this format when presentation and protection both matter.

Each mailer weighs approximately 0.58 lbs. Sold in bundles of 50, the pack size supports efficient shelf storage and consistent replenishment in moderate-to-high volume shipping environments. These mailers ship via parcel carrier.
