These storage bins are a good deal. I bought a set of 6 last year. I thought 6 would be too many; 6 was not enough. But the boxes have been sold out ever since. I find these recently, which are almost exactly the same. I still prefer the originals -- which were green with slightly different handles -- but these will definitely do. They stack well, and items stack well inside of them. They are the perfect size for hanging files, and are wide enough that several thick files will fit inside. They are very useful, and it is good that they are see through. If you're looking for the size that will fit books and files, this is it.
