These kraft mailing tubes feature a 3 inch inside diameter and 30 inches of usable interior length, built with 3-ply spiral wound construction and a 0.070" wall thickness. That wall spec delivers meaningful structural rigidity while keeping per-unit weight low — an important factor for rolled goods shipped at volume.

The included white snap-on end caps are engineered to stay secured throughout transit, protecting contents from exposure or impact at the tube ends. Posters, architectural drawings, blueprints, fabric samples, and fine art prints all ship reliably in these tubes without requiring additional protective wrapping around the ends. The listed 30 inch dimension reflects usable interior space; actual tube length is slightly longer to accommodate the end caps.

Tubes are reusable and recyclable, making them a practical choice for facilities with sustainability targets. Each case contains 24 tubes. Replacement 3" end caps are available separately for high-volume operations that cycle through caps independently of the tubes.
