18 x 13 x 5 Corrugated Boxes 25/Bundle

These corrugated boxes are standard test RSC (Regular Slotted Carton) in a classic brown color. They meet Federal Mil Spec PPP B 636. All sizes come flat, making them super easy to store and ship. The sizes mentioned are the inside dimensions of the box, listed as Length, Width, and Height.

To use these corrugated boxes, first unfold them from their flat - packed state. Then, fold along the creases to form the box shape and secure the bottom flaps. You can use them to store or ship a variety of items. When packing, make sure not to overfill the boxes to avoid damage during shipping. For storage, keep them in a dry place away from direct sunlight to prevent the cardboard from weakening. If the boxes get dirty, you can gently wipe them with a dry cloth.
