The 12 x 10 x 4 inch Kraft Deluxe Literature Mailer is built from ECT-32-B single wall kraft corrugated board, delivering a rigid, crush-resistant enclosure with interior dimensions that comfortably fit standard letter-size documents, oversized folios, catalogs, and similarly proportioned flat or low-profile items with room for inserts or light padding.

The deluxe construction features protective side flaps paired with a front outside tuck closure that secures the mailer without tape, glue, or staples — reducing pack station labor and keeping presentation clean. This format suits high-volume fulfillment operations, retail distribution, office supply workflows, and direct-to-consumer shipments where a professional unboxing appearance matters.

Each mailer weighs approximately 0.54 lbs and is sold in bundles of 50, supporting both recurring stock programs and project-based purchasing. The consistent kraft surface accepts standard shipping labels without additional surface prep.
