These kraft mailing tubes feature a 3-inch inside diameter and 18 inches of usable interior length, built with 3-ply spiral wound kraft construction at .070-inch wall thickness. The rigid cylindrical form resists crushing under transit pressure, and white snap-on end caps are included with every tube — engineered to stay secured through standard parcel handling without adhesive.
Ideal for shipping and storing rolled documents, architectural blueprints, engineering drawings, posters, artwork, fabric swatches, and film. Well-suited for print shops, architecture and design firms, fulfillment operations, and academic or government mail centers that regularly send oversize flat materials in rolled format.
The listed 18-inch length reflects usable interior space; actual tube length is slightly longer to accommodate the end caps. Tubes and caps are both reusable and recyclable. Replacement 3-inch end caps are available separately for high-volume programs. Sold in cases of 24, shipped via parcel carrier.
