12 x 9 x 4 Corrugated Boxes 25/Bundle

All these boxes are standard test RSC (Regular Slotted Carton) brown corrugated boxes that meet Federal Mil Spec PPP B 636. They're shipped flat, making storage and shipping a breeze. The sizes mentioned are the inside dimensions - length, width, and height.

These corrugated boxes are super easy to use. First, unfold the box from its flat - shipped state. Then, fold the flaps at the bottom to form a base and secure them. You can use packing tape to seal the bottom firmly. For storing, you can keep them flat until you need to use them, which saves a lot of space. When it comes to shipping, make sure your items fit well inside the box according to the given inside dimensions. After use, if you want to reuse the boxes, just flatten them again and store in a dry place. Avoid getting the boxes wet as it can weaken the corrugated structure.
