These white mailing tubes feature a 3 inch inside diameter and 36 inches of usable interior length, built from 3-ply spiral wound fiberboard at .07" wall thickness. That construction delivers rigid resistance to bending and compression, keeping rolled contents intact through the full handling cycle. The listed 36 inch length reflects usable interior space — actual tube length is slightly longer to accommodate the included white snap-on end caps.

These tubes are well suited for architecture, engineering, and print fulfillment operations that need to ship or store rolled drawings, blueprints, posters, and large-format documents. They also see regular use in retail distribution and e-commerce fulfillment for cylindrical or scroll-format products requiring firm, damage-resistant packaging.

Each tube ships with white snap-on end caps that seat securely and hold through standard parcel handling. Tubes and caps are both reusable and recyclable. Replacement 3" end caps are available separately for high-volume or multi-use programs. Sold in cases of 24.
