20 x 4 x 4 Corrugated Boxes 25/Bundle

These brown corrugated boxes are standard test RSC (Regular Slotted Carton) 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 great for storing and shipping various items. To use them, simply unfold the flat - packed boxes and assemble them according to the natural folds. When packing, make sure not to overfill the boxes to avoid damage during handling. For storage, keep them in a dry place to prevent the corrugated material from getting wet and losing its strength. You can stack them safely, but don't stack too high to prevent the bottom boxes from collapsing.
