I bought these to organize documents for tax purposes. They are perfect for that. The snap lids go on and off easily and the containers and sturdy enough to stack to save room.
These boxes are perfect to move my company. Unfortunately the 4th box down had the corner chipped off. I didn't return because the 1st three boxes were perfect but mostly because I wasn't going to unpack those three boxes of files. Moving is bad enough but this has just made it a bit more difficult. Sorry.
