These 1 1/2 inch inside diameter kraft mailing tubes are built from 3-ply spiral wound kraft board, producing a rigid, crush-resistant cylinder suited for rolled documents, blueprints, artwork, film, and similar materials. White snap-on plastic end caps are included and engineered to seat securely without popping off during transit.

Print shops, engineering firms, architecture studios, retail distributors, and e-commerce operations shipping posters or technical drawings rely on these tubes to protect contents from bending and surface damage. The consistent 1 1/2" bore accommodates standard rolled-document diameters across a variety of fulfillment environments.

Listed length reflects usable interior space — actual tube length is slightly longer to accommodate cap seating. Tubes are reusable and fully recyclable. Additional 1 1/2" end caps are available separately for replenishment stock. Sold in cases of 50.
