Made of 3-ply spiral-wound fiberboard, Round Tubes protect photos, artwork and paper documents against folds, creases and tears. Also functional for parts and other supplies. When used in a marketing application, the white color enhances the presentation of your product(s). Each tube includes two snug-fitting plastic end plugs. Tube diameter and length are inside dimensions. In determining the length, allow an extra inch on each end to leave space for the end plugs and to protect the edges of your contents. Optional end closures include metal caps and Snap-Seal Tubes. A custom item, see Quote Request Form. Minimum quantities may apply. Also see, Round Tubes (Kraft) and Round Tubes (Colors).
