These 2 x 9 inch blue mailing tubes offer a practical color-coding solution for operations that route, sort, or categorize shipments by department, project, or recipient type. Each tube is 3-ply spiral wound with a .060" wall thickness, delivering consistent crush resistance through postal and courier handling.

The 2" interior diameter fits rolled documents, blueprints, posters, and artwork — making these tubes a reliable choice for print shops, architectural firms, engineering offices, and fulfillment operations that ship flat goods in cylindrical format. Color differentiation at the tube level simplifies intake sorting and reduces mislabeling on the receiving end.

White plastic end caps are included and seat securely to protect contents in transit. All dimensions reflect usable interior measurements; the actual tube is slightly longer to accommodate the end caps. Additional 2" caps are available separately for high-volume operations requiring replacement closures. Sold in cases of 50.
