The 12 x 10 x 4 inch White Deluxe Literature Mailer is a self-locking corrugated mailer built from ECT-32-B white corrugated board. Front locking tabs secure the closure without tape, glue, or staples, while reinforced side flaps add stacking strength to protect contents during transit and storage. The mailer assembles in seconds, making it well-suited for high-volume shipping and fulfillment environments.

This mailer is a practical fit for publishers, trade suppliers, marketing teams, and B2B fulfillment operations shipping catalogs, brochures, bound documents, flat sample kits, and business correspondence. The bright white exterior presents cleanly for branded or unbranded outbound shipments, making it equally useful for retail direct-to-consumer orders and professional account mailings.

Constructed from single wall ECT-32-B corrugated board, the mailer delivers reliable crush resistance without excess weight, approximately 0.55 lbs. Bundles of 50 allow efficient inventory management for operations with recurring volume needs.
