These 5 x 5 x 43 inch white square mailing tubes are built from ECT-32-B white corrugated board and assemble without tape or glue, eliminating adhesive consumables from the packing process. The square profile prevents rolling during handling and staging, a practical advantage over round tube formats on busy pack lines.

The 43-inch length and 5 x 5-inch interior cross-section make these tubes well suited for posters, architectural drawings, banners, calendars, and rolled textiles. The clean white exterior supports retail distribution, e-commerce fulfillment, and direct-to-consumer shipments where presentation matters at the point of receipt.

Each tube weighs approximately 0.848 lbs. and ships flat to minimize storage footprint before assembly. Tubes are parcel-friendly and sold in bundles of 25 to support consistent inventory management for warehouses and distribution centers processing regular outbound volume.
