Keep your artwork, drafts and blueprints looking good when you transport them to and from your studio in Safco's Telescoping Document Tube. Adjust the polyethylene tube from 24 1/2 inches to 40 inches to best fit your files; locking tabs keep it in place. The twist lid has a reusable snap cap label so you can quickly identify stored files. An adjustable shoulder strap makes the document tube a cinch to carry.
