4 1/2 x 4 1/2 x 72 TelescopIng Outer Boxes 25/Bundle

Each set consists of one inner and one outer carton, sold separately. Made from 200#/ECT - 32 kraft corrugated material. The cartons feature a full over lap (FOL) bottom for enhanced strength.

These telescoping outer boxes are really easy to use. First, take out the inner and outer cartons from the bundle. You'll need one of each to make a set. Simply place your items inside the inner carton and then slide it into the outer carton. Remember, the cartons are sold separately, so make sure you have both. As for maintenance, keep them in a dry place to avoid any damage to the kraft corrugated material. The full over lap bottom gives extra strength, but don't overload the boxes to maintain their durability.
