18 x 18 x 6 Multi Depth Corrugated Boxes 20/Bundle

These brown corrugated boxes are standard test RSC (Regular Slotted Carton) and meet Federal Mil Spec PPP B 636. They're great for shipping and storage. All sizes are shipped flat, making them super easy to store and ship. The dimensions shown are the inside length, width, and height of the box.

How to use these boxes: First, unfold the box carefully. Then, fill it with your items. You can use packing tape to seal the box for shipping. When storing, just keep them in a dry place. They come flat, so you can stack them easily. Don't overfill the box as it might break. If you get them wet, let them dry completely before using again. Also, try to handle them gently to avoid any damage to the corrugated structure.
