37 x 4 x 30 TelescopIng Inner Boxes 10/Bundle

Each set needs one inner and one outer carton, sold separately. Crafted from 200#/ECT - 32 kraft corrugated, these cartons feature a full over lap (FOL) bottom for extra strength.

To use these telescoping inner boxes, simply pair one inner carton with one outer carton to form a set. You'll need to buy them separately. When packing items, you can take advantage of the extra strength provided by the FOL bottom. As for maintenance, keep them in a dry place to prevent the kraft corrugated material from getting damaged. Avoid over - stuffing the boxes to maintain their shape and integrity. That way, they'll serve you well for a long time.
