3 x 3 x 18 Square White Corrugated Mailing Tube 25/Bundle

These square white corrugated mailing tubes are a great choice for your shipping needs. Their square shape makes inserting and removing items a breeze. They ship flat, taking up less space during storage and transit. They can rest stably on flat surfaces without rolling off and are easily stackable, which helps you save space and organize your packages efficiently.

Using these mailing tubes is easy. First, open up the flat - shipped tube and assemble it into its square shape. You can then insert your items into the tube. Make sure your items fit well and are not too large to avoid damaging the tube. When it comes to storage, since they ship flat and stack easily, you can keep them in a corner or on a shelf without taking up much room. To maintain them, keep them in a dry place to prevent the corrugated material from getting damp and losing its strength. Also, be careful when handling sharp objects near the tubes to avoid puncturing them.
