When standard mailing tubes aren't enough, Heavy Duty Kraft Mailing Tubes deliver the extra protection that oversized, heavy, or high-value contents demand. Built with an extra-strong, three-ply spiral wound construction, these rigid tubes are engineered to resist bending, crushing, and any rough handling that can occur during transit. This makes them the go-to choice for architects, engineers, photographers, artists, and businesses shipping rolled documents, blueprints, artwork, or large-format prints.
