These kraft mailing tubes feature a 3-ply spiral wound construction and a crimped end closure system that seals by compressing each end — no tape, adhesive, or separate end caps required. The 4 inch inside diameter and 30 inches of usable interior length make this one of the larger-format standard tube sizes available for rolled goods shipments.

Well suited for print shops, architectural firms, fulfillment centers, and art supply distributors, these tubes protect blueprints, engineering drawings, posters, canvas prints, fabric swatches, and similar rolled materials during transit and storage. The kraft material is reusable and recyclable, supporting sustainable packaging programs.

Each case contains 15 tubes and weighs approximately 13.6 lbs. The actual tube body is slightly longer than the stated usable length to accommodate the crimped closure at each end. Cases ship via parcel carrier.
