18 x 18 x 18 Corrugated Boxes 20/Bundle

These boxes are standard test RSC (Regular Slotted Carton) brown corrugated and meet Federal Mil Spec PPP B 636. They're shipped flat, making them super easy to store and convenient to ship. 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 align the edges properly and secure them with tape. You can use these boxes to store various items like clothes, books, or small electronics. When packing, try to distribute the weight evenly to avoid the box from tipping over. For shipping, add some cushioning material inside to protect your items. As for maintenance, keep the boxes in a dry place to prevent the corrugated material from getting damp and losing its strength. If the boxes get dirty, you can gently wipe them with a dry cloth.
