I buy these boxes to sort out materials. Not so expensive that I can let friends "take the box". Sometimes I think they take the stuff just to get my box.
I rely on these for business and personal use all old financial records that need to be kept (and kept out of the way!) old correspondance files from work that I may have to access later. It gives me a sense of security to know that I can fille and label these and that I can access records I need seldom without having them intrusdre on my living space.
I am a teacher and bought these boxes to hold school supplies. They are sturdy enough to hold my workbooks student reading books office supplies etc. They are also easy to label and stack nicely in a storage area. Having bought them in the beginning of January I also used some of them for storing Christmas items. I feel confident that my decorations and my workbooks are safe and will be well protected when I go to retrieve them next year. If needing boxes for storing papers books toys decorations etc. these boxes would fit that requirement. I personally would not store breakables in them but that isn't what they are designed for any way.
