3 x 30 1/4 Triangular White Corrugated Mailing Tube 50/Bundle

These 200 lb. test white corrugated mailing tubes feature a triangular design for easy item insertion and removal. They ship flat, saving space. Once assembled, they sit securely on flat surfaces without rolling. The heavy - duty triangular shape provides extra side protection. Note that all sizes are based on the mailers' inside usable dimensions (diameter x length).

Using these triangular mailing tubes is easy. First, take them out of the flat - packed bundle. Then, assemble them according to the natural folds. You can easily insert your items into the tube because of its triangular shape. When shipping, place it on a flat surface, and it won't roll off. As for maintenance, keep them in a dry place to prevent the corrugated material from getting wet. Also, be careful not to over - stuff the tubes as it might damage the triangular structure. Always refer to the inside usable dimensions when choosing what to put inside.
