Use for business document storage. At home use them for personal storage. I friend was moving and used these as boxes to pack his entire household into.
Box tears when trying to separate the perforated portions of both the box and cover. Even when being extra careful and folding the cover back and forth multiple times to separate it from the box it still tears.
Boxes of the same size make it easier to pack a moving truck and easier to carry in and out. Good labeling makes for easy organization of room and item.
