These white mailing tubes feature a 4 inch inside diameter and 18 inches of usable interior length, built from 3-ply spiral-wound construction with a 0.08" wall thickness. That wall depth delivers shipping-grade rigidity without excessive weight, keeping rolled or cylindrical contents protected from crushing or distortion in transit. The listed 18 inch length reflects usable interior space; actual tube length is slightly longer to accommodate the included snap-on white end caps.

The snap-on caps are engineered to stay firmly seated throughout shipment, preventing contents from shifting or becoming exposed. These tubes are well suited for art prints, architectural drawings, diplomas, posters, fabric swatches, and any rolled document or cylindrical product requiring a clean, professional presentation. E-commerce sellers, print shops, framing studios, and document management operations are among the most common users.

Each tube and cap set is reusable and recyclable. Replacement 4" end caps are available separately for multi-use workflows. Sold in cases of 15 tubes, with caps included, and ships via parcel carrier.
