21 x 15 x 15 Corrugated Boxes 20/Bundle

These brown corrugated boxes are standard test RSC (Regular Slotted Carton) and meet Federal Mil Spec PPP B 636. They ship flat, making them easy to store and transport. The sizes given are the inside dimensions in the order of length, width, and height.

To use these boxes, simply unfold them and assemble according to the creases. You can use them to pack a variety of items for storage or shipping. When packing, make sure not to overload the boxes to avoid damage. For storage, keep them in a dry place to prevent the corrugated material from getting wet and losing its strength. If the boxes get dirty, you can wipe them with a dry cloth. That's all there is to it!
