These boxes are super handy for almost every organizing project. When I begin working with a new client I grab a 10 pack of these to bing to the job. The reason they are so handy is that even when completely filled with heavy books I can still easily move and haul them around the project. Also - they make sorting a snap. Once we are done with them they collapse down to be stored for future organizing projects!
The boxes were easy to assemble. The first one or two had a learning curve but the instructions are simple. The boxes hold up nicely under weight. I had about 50 ponds in a couple and they maintained their form and rigidity.
I found Staples had the best price on the one cubic foot "banker's boxes". When I move I prefer using these to medium sized cardboard boxes for my files magazines books small household items and even some clothing which can get too heavy for me to lift. These boxes are compact stackable have slits for handles and space for clear labeling (less advertising cluttering up the sides). Once I have moved if I empty them they can be collapsed and reusable without adding box tape. When Staples have them on sale it's an even better bargain.
