7 3/8 x 7 3/8 x 1 3/8" Kraft Literature Mailers

These kraft literature mailers feature a square footprint with a shallow 1 3/8" depth, built from ECT-32-B single wall corrugated board. The rigid B-flute construction keeps contents protected without adding bulk, and the self-locking closure assembles without tape, glue, or staples.

The shallow profile makes these mailers well-suited for media, photos, certificates, notecards, and other flat or low-profile items. E-commerce fulfillment centers, office supply distributors, print shops, and retail replenishment operations all benefit from the consistent square format and tool-free assembly at high-volume pack stations.

Each mailer ships flat for efficient storage and is sold in bundles of 50. At approximately 0.15 lbs, the lightweight construction supports weight-conscious shipment planning. The natural kraft finish presents a clean, professional appearance for both direct-to-consumer and business-to-business applications. Ships via parcel.
