These jumbo kraft mailing tubes measure 5 inches inside diameter with 30 inches of usable interior length, built from .125" thick 3-ply spiral wound kraft construction. The spiral wound process bonds three plies into a rigid cylindrical wall that resists bending, crushing, and compression under the stresses of transit and storage.

The 5 inch bore handles oversized rolled materials that standard 2 or 3 inch tubes cannot accommodate — making these well suited for print shops shipping large-format posters and blueprints, textile distributors rolling fabric samples, engineering firms archiving CAD drawings, and manufacturers packaging cylindrical components or artwork.

Listed length reflects usable interior space; actual tube length is slightly longer to accommodate the included end caps. Each case contains 15 tubes at approximately 24.96 lbs per case, and the product ships via parcel carrier.
