These white mailing tubes measure 4 inches in inside diameter with 24 inches of usable interior length — the actual tube is slightly longer to accommodate the depth of the included snap-on end caps. 3-ply spiral wound construction and .08" thick walls deliver consistent crush resistance along the full tube length, protecting rolled contents from edge to edge.

The secure snap-on caps are engineered to stay in place throughout transit, making these tubes well-suited for architects, engineers, print shops, and photography studios shipping rolled drawings, blueprints, fine art prints, and large-format documents. Distribution centers and e-commerce operations also use them for cylindrical retail products and poster fulfillment.

Tubes are reusable and recyclable, supporting return-shipment workflows and sustainability programs. Replacement 4" end caps are available separately for high-volume or multi-use operations. Cases contain 15 tubes and ship via parcel carrier.
