20 x 20 x 20 Heavy Duty Boxes 10/Bundle

These boxes are heavy-duty RSC brown corrugated. They ship flat, making storage and shipping a breeze. The sizes listed are the inside dimensions in length, width, and height order.

These heavy - duty boxes are great for various uses. For packing, simply unfold the box, seal the bottom flaps, and start placing your items inside. Make sure not to over - load the box as it may cause the box to break. When storing the boxes, keep them in a dry place to prevent the corrugated material from getting wet and losing its strength. If you're shipping items, use strong packing tape to seal all the edges properly. After use, you can flatten the boxes again for easy storage until next time.
