15 x 12 x 4 Corrugated Boxes 25/Bundle

These corrugated boxes are standard test RSC (Regular Slotted Carton) and come in a classic brown color. They meet Federal Mil Spec PPP B 636. All boxes ship flat, which makes them super easy to store and transport. The sizes listed are the inside dimensions - length, width, and height.

Using these corrugated boxes is a breeze. First, unfold the box and make sure all the flaps are in place. You can use them to pack various items like books, clothes, or small electronics. When packing, try to distribute the weight evenly to prevent the box from tipping over. For storage, keep them in a dry place away from direct sunlight to avoid damage. If you need to stack the boxes, make sure the bottom one is strong enough to support the weight on top. That's all there is to it!
