Boxes are not the quality you'd expect from Staples. I loaded hanging files in each box and the sides collapsed. Maybe I put too much in them but not more than what they show in pictures. Or maybe they're not made for hanging files? I had to find another way of storing the files and had to throw all of these away.
The boxes are good but not heavy duty. The lip for the lid should be longer maybe 2 1/2-3 inches to keep the cover on well. Folding them takes a little practice but once you get the hang of it it pulls together well
