18 x 12 x 3" White Literature Mailer

The 18 x 12 x 3 inch white literature mailer is constructed from ECT-32-B single wall corrugated board and features a self-locking tab closure that secures without tape, staples, or additional supplies — keeping assembly fast and pack stations uncluttered.

The interior footprint makes this mailer a practical fit for catalogs, bound documents, folded apparel, and flat retail goods. Its clean white exterior suits both branded and unbranded outbound fulfillment, and the 3" depth handles low-profile items that standard RSC boxes would crush or leave poorly packed.

Each mailer weighs approximately 0.57 lbs. Sold in bundles of 25, with a consistent pack count that simplifies inventory tracking and reorder planning.
