These 3 x 3 x 48 inch white square mailing tubes are built from ECT-32-B white corrugated board and fold together without tape or glue, eliminating adhesive prep steps and reducing assembly time at the packing station. Tubes ship flat to minimize storage footprint until needed.
The square profile keeps tubes stationary on packing surfaces and prevents rolling during transit — a practical advantage over round tube formats. Posters, blueprints, banners, architectural drawings, fabric samples, wooden dowels, metal rods, and other long narrow items fit cleanly within the 3" x 3" interior opening. These tubes are well suited to e-commerce fulfillment, print distribution, retail replenishment, and light manufacturing outbound shipping.
Constructed from ECT-32-B corrugated board, each tube weighs approximately 0.62 lbs, supporting dimensional weight management for parcel shipments. The listed 48" length reflects usable interior. These tubes seal closed without end caps. Each bundle contains 25 tubes.
