The 12 x 12 x 2 inch kraft literature mailer is built from ECT-32-B single wall corrugated board, delivering rigid structure that protects flat and low-profile contents throughout transit. The self-locking tab closure with integrated side flaps secures the mailer without tape, glue, or staples, eliminating consumables and reducing pack-out steps on high-volume lines.

The square footprint is well-suited for catalogs, art prints, bound documents, sample kits, photo prints, vinyl records, and folded apparel. E-commerce retailers, publishers, promotional product distributors, and B2B fulfillment operations all find consistent use for this format.

Each mailer weighs approximately 0.39 lbs. Bundles of 50 support inventory planning and per-unit cost tracking for procurement teams managing recurring mailing programs.
