The structure and support ribs give this box good capacity (about 1/2 a lateral file drawer per box) it remains to be seen how durable the material is since I have only just purchased them. The handles that latch the bin and lid are very easily knocked loose which is a nuisance during active loading/unloading and does not bode well for storage. Stacking is not quite as secure as other brands.
The handle snapped right off and is very difficult to snap back in place. The box seems solid but the handles are flimsy and seem likely to pop off again. I will not be buying another!
Had to move my home office. Bankers boxes just weren't cutting it the covers don't fit over pendaflex folders. These boxes were strong and just the right size.
