These kraft mailing tubes feature a 4 inch inside diameter and 12 inches of usable interior length, built with 3-ply spiral wound construction and an .080" wall thickness for reliable rigidity during shipping and handling. White snap-on end caps are included and engineered to stay firmly seated in transit without popping off. Actual tube length exceeds the listed interior dimension to accommodate the caps.

These tubes are well suited for shipping, mailing, and storing rolled documents, architectural drawings, blueprints, posters, and fabric samples. They serve fulfillment centers, print shops, architecture and engineering firms, and retail operations that need dependable protection for cylindrical or rolled goods.

The tubes are reusable and recyclable, supporting sustainability goals in packaging programs. Additional 4 inch end caps are sold separately for operations requiring replacement caps or higher-volume throughput. Each case contains 15 tubes and ships via parcel carrier.
