21 x 13 x 13 Corrugated Boxes 20/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, ensuring high - quality. All boxes ship flat, making storage and shipping a breeze. The given sizes (21 x 13 x 13) are the inside dimensions, presented as Length, Width, and Height.

To use these boxes, simply unfold them from their flat - packed state. You can start by aligning the flaps and securing them with tape. They're great for storing various items like books, clothes, or even fragile items if you add some padding. When shipping, make sure to seal the boxes tightly to prevent any contents from falling out. For storage, keep them in a dry place to avoid any water damage. If they get dirty, you can use a dry cloth to wipe them clean. Don't overload the boxes beyond their capacity to avoid tearing or breaking.
