18 x 12 x 3 Corrugated Boxes 25/Bundle

These boxes are standard test RSC brown corrugated boxes that meet Federal Mil Spec PPP B 636. They ship flat, making them super convenient for storage and shipping. The dimensions shown are the inside length, width, and height of the box.

To use these corrugated boxes, first unfold them and assemble the bottom flaps according to the folding lines. You can then place your items inside the box. Make sure to fill any empty spaces with packing materials to prevent the items from moving around during shipping. When storing these boxes, keep them in a dry place to avoid moisture damage. Since they ship flat, they can be stacked easily to save space. If you need to reuse the boxes, check for any signs of damage before using them again. If there are minor damages, you can reinforce the box with tape.
