16 x 16 x 40 TelescopIng Inner Boxes 10/Bundle

Each set requires 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 extra strength.

To use these telescoping inner boxes, first get both the inner and outer cartons as they are sold separately. Put your items inside the inner box and then place it into the outer carton. This setup is great for keeping your stuff secure. When handling, be careful not to over - load the boxes as it might affect the FOL bottom's strength. To maintain them, keep the boxes in a dry place. If they get wet, the kraft corrugated material might weaken. And that's all you need to know to make the most of these boxes!
