These kraft mailing tubes feature a 1 1/2 inch inside diameter and 15 inches usable interior length, built with 3-ply spiral wound walls at 0.060" thickness. That wall construction delivers consistent rigidity, keeping cylindrical and rolled contents protected through the demands of the mail stream.

The included white plastic snap-on end caps are engineered to stay seated during transit, reducing the risk of content loss or damage. Because the caps remove cleanly without tearing the tube body, the tubes are well suited for reuse across multiple fulfillment cycles — practical for e-commerce operations, print and photo studios, architectural firms, and retail distribution centers that ship rolled documents, posters, blueprints, or fabric samples.

Each case contains 50 tubes with caps included. The listed 15" length reflects usable interior space; actual tube length is slightly longer to accommodate the end caps. Replacement 1 1/2" end caps are available separately for high-volume operations that cycle tubes repeatedly.
