18 1/2 x 12 1/2 x 12 Corrugated Boxes 20/Bundle

These boxes are standard test RSC (Regular Slotted Carton) brown corrugated and meet Federal Mil Spec PPP B 636. They ship flat, making storage and shipping a breeze. The sizes listed are the inside dimensions - length, width, and height.

These corrugated boxes are super useful for storing or shipping items. To use them, simply unfold the box along the creases. Then, fold the flaps at the bottom and tape them securely. You can put your items inside and close the top flaps in the same way. When storing these boxes, keep them in a dry place to prevent any damage. Avoid getting them wet as this can weaken the corrugated material. Also, don't stack heavy objects on top of them to prevent crushing. If they get dirty, you can gently wipe them with a dry cloth.
