4 x 42 Brown Mailing Tubes With End Caps .080 Gauge 15/Case

These durable 3-ply spiral wound mailing tubes are perfect for protecting sketches, blueprints, graphs, posters, and important documents. The plastic end caps have a friction fit, staying on during mailing, and their flat surfaces are great for writing. These rigid tubes resist folding or bending and can be reused. The listed sizes are the usable dimensions after inserting the end caps.

Using these mailing tubes is easy. First, slide your sketches, blueprints, or other documents gently into the tube. Then, press the plastic end caps firmly onto the tube ends. When writing on the caps, use a pen or marker that won't smear. For reuse, just remove the end caps, take out the contents, and clean the tube with a dry cloth if needed. Keep these tubes in a dry place to prevent any damage from moisture. Avoid dropping or applying too much pressure on the tubes to maintain their shape and rigidity.
