These storage boxes are strong stackable and a good value especially when they're on sale. Staples please don't ever stop making them. They could be slightly deeper but they are excellent for storage. I would recommend them particularly if you are not going to store really heavy things such as tools or a sewing machine. I use them primarily to store my children's school/artwork; out-of-season clothes; almost anything!
I'm a teacher and I am using these boxes to organize my files by month. They turned out to be a little smaller than I had anticipated but are still useful and a great value.
