These boxes are handy for more than document storage. Because they can be opened up and then stored again flat they are also good for temporary tasks. I have used them to help me sort through paperwork and organize multiple projects at year's end; put kids' toys into categories of "keep"/"donate"/"sell" at regular growth & maturity intervals; and loaded them up with supplies when we drive to our vacation home -- makes it easy to stack and transport as well as carry into the house upon arrival.
These storage boxes are the best I have ever seen. You can use them for all your personal or business projects. They hold all sizes of folders envelopes bags or any other container of paperwork. This is by far the best box in the world as far as I am concerned. Easy to put together. Strong enough to put up with all the paper items that you need to keep. I have depended on the Staples boxes for most of my life and I have never been disappointed. This is the box that all of us need to do the storage game and do it well!!!!!!
My go to box for everything from files storage and moving. Stacks easily. Just the right size for most items. Store books files and whole house full of stuff. Can be used over and over holds up really well even with heavy books.
The boxes have good capacity and are easy to assemble. Staples should provide coupons for these everyday products not just the high end office machines and electronics.
