These heavy-duty kraft mailing tubes measure 3 inches inside diameter with a 72 inch usable interior length. The .125" thick, 3-ply spiral wound wall delivers rigid, crush-resistant protection that substantially exceeds standard mailing tube construction — end caps are included with every tube.

The 72 inch length makes these tubes well-suited for blueprints, architectural drawings, large-format prints, fabric rolls, and oversized posters. Print shops, engineering firms, architectural studios, and manufacturing facilities rely on this format for both outbound shipments and long-term rolled-material storage.

Each tube's spiral wound kraft composite resists bending and deformation under load. The listed 72 inch length reflects usable interior space; the actual tube is slightly longer to accommodate the end caps. Cases contain 15 tubes.
