These 24 x 4 x 4 inch white corrugated mailers are built from ECT-32-B single wall corrugated board and feature a one-piece fold-lock design that closes securely without tape, glue, or staples. Assembly takes seconds, supporting consistent throughput in high-volume packing environments.

The elongated format is well-suited for posters, rolled textiles, dowels, architectural prints, long-run retail products, and other tubular or linear items that standard RSC boxes cannot accommodate. The white exterior provides a clean, retail-ready presentation appropriate for direct-to-consumer shipments, wholesale fulfillment, and branded packaging programs.

When folded, the mailer creates double wall panels along the front and sides, improving crush resistance during transit. Each mailer weighs approximately 0.49 lbs, which helps manage dimensional weight costs. Mailers are sold in bundles of 50 and ship via parcel carrier.
