These white mailing tubes measure 1 1/2 inch inside diameter with 24 inches of usable interior length. Built from 3-ply spiral wound chipboard at .06" wall thickness, they deliver consistent rigidity that protects cylindrical contents against crushing and distortion. The white exterior projects a clean, professional appearance on arrival.

Matching white snap-on end caps are included with every tube and engineered to stay firmly seated through parcel handling. The listed 24" length reflects usable interior space — the actual tube extends slightly beyond that to accommodate the cap fit. Ideal for architects, engineers, photographers, print shops, and fulfillment operations shipping rolled documents, blueprints, posters, artwork, and fabric samples.

Tubes are constructed from recyclable materials, and the caps are reusable for multi-use or return-shipping workflows. Replacement 1 1/2" end caps are sold separately. Cases contain 50 tubes and ship via parcel carrier.
