4 x 4 x 37 Square White Corrugated Mailing Tube 50/Bundle

These square-shaped mailing tubes make inserting and removing items a breeze. They ship flat, saving you valuable space. Once assembled, they sit firmly on flat surfaces without rolling away and can be stacked easily for convenient storage and shipping.

To use these mailing tubes, first unfold them from their flat - shipped state. You can then insert your items easily thanks to the square shape. When packing, make sure your items fit snugly to prevent movement during shipping. To store, simply flatten them again to save space. Keep them in a dry place to avoid any damage to the corrugated material. Avoid exposing them to extreme temperatures as this could affect their structure.
