18 x 18 x 4 Corrugated Boxes 25/Bundle

These brown corrugated boxes are standard test RSC (Regular Slotted Carton) and meet Federal Mil Spec PPP B 636. They're shipped flat, making storage and shipping a breeze. The dimensions shown are the inside length, width, and height of the box.

Using these boxes is easy. First, unfold the box from its flat - shipped state and assemble it according to the creases. You can use them to store various items like books, clothes, or office supplies. When shipping, make sure to pack your items securely to prevent damage. As for storage, since they come flat, you can stack them neatly in a corner. Keep them in a dry place to avoid moisture damage. If the boxes get dirty, you can wipe them with a dry cloth. These boxes are built to last, but avoid overloading them beyond their capacity to maintain their structural integrity.
