Every time I move store or help a friend move I go to Staples for boxes. They are just the right size for most things. I cannot overpack them and with side handles they are easy to pick up and move. My wife likes rthem too because they are easy for her. Do yourself a favor and get some Staples bubble wrap with the sticky side. It is perfect for small items that need to be protected. No one else seems to have it.
I'm a professional organizer and these banker boxes are my favorite! I use them to help people sort and categorize their belongings. They are the most sturdy that I've found.
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!
