18 x 18 x 12 Multi Depth 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 super easy to store and transport. The sizes mentioned are the inside dimensions of the box, listed as Length, Width, and Height.

To use these boxes, first unfold them from their flat - shipped state. Make sure to fold along the pre - scored lines for a proper fit. You can use packing tape to seal the bottom of the box before loading your items. When loading, try to distribute the weight evenly to prevent the box from tipping over during transit. As for storage, keep them in a dry place away from direct sunlight. If the boxes get wet, they may lose their strength. There's no special maintenance required, but avoid rough handling to keep them in good condition for reuse.
