These white mailing tubes feature  1 1/2 x 6 inch usable interior dimensions, built from 3-ply spiral wound fiberboard with a .06" wall thickness. The spiral wound construction produces a rigid, lightweight cylinder that resists crushing under normal transit and storage pressure.

Snap-on white end caps are included with each tube and engineered to stay secured during shipment without tape or additional closure. The secure cap fit makes these tubes well suited for rolling plans and drawings, posters, certificates, film strips, and slender rigid items shipped through e-commerce fulfillment, print shops, government agencies, and retail distribution operations.

Listed length reflects usable interior space; actual tube length is slightly longer to accommodate the end caps. Tubes are reusable and recyclable. Additional 1 1/2" end caps are sold separately for high-volume operations requiring replacements. Cases contain 50 tubes and ship via parcel carrier.
