text: They fit in my filing system and are terrific for storing important things like warranties, directions and extra parts: washers for a hose nozzle which otherwise I would lose. I put in started letters, notes to take with me ie: to the doctor ect., a pen, + any information I receive. I can see what is in there or write with a permanent marker what's in it. I'm sure I'll think of other things to use them for perhaps small quilt squares I am sewing. So far no problem with the zippers and they're not going to fall apart.
