These kraft mailing tubes feature a 4 inch inside diameter and 12 inches of usable interior length, built with 3-ply spiral wound paperboard construction that delivers consistent wall rigidity under the compression and handling stresses of transit. The crimped end closure seals by hand pressure alone — no tape, adhesive, or separate end caps required.

The self-sealing design makes these tubes practical for print shops, architectural firms, photography studios, and fulfillment operations shipping rolled documents, blueprints, posters, artwork, and fabric swatches. The listed 12 inch length reflects usable interior space; actual tube length is slightly longer to accommodate the crimped ends.

Tubes are reusable and fully recyclable, supporting facility-level sustainability programs. Sold in cases of 15 and parcel-friendly for standard restocking workflows.
