The 12 x 11 x 3 inch Kraft Deluxe Literature Mailer is a self-locking corrugated mailer built for shipping flat and low-profile items without tape, glue, or staples. Constructed from ECT-32-B kraft corrugated board, it delivers rigid structural protection during transit while keeping pack-out time to a minimum.

The tab-locking front outside tuck closure and protective side flaps make this mailer a practical choice for high-volume operations in e-commerce fulfillment, retail replenishment, warehouse distribution, and manufacturing environments — particularly where documents, catalogs, printed materials, binders, and similarly sized packaged goods move in consistent volume.

Each mailer weighs approximately 0.41 lbs and ships via parcel carrier. Sold in bundles of 50, providing a dependable tape-free solution at scale.
