I use these for school and they help keep my stuff in place. It saves the hassle of constantly needing a hole puncher. They are convenient and easy to use. I use a write-on tab on the side for dividers so I don't have to buy new dividers every semester as the number of classes I take change.
I bought these binder pockets for our bell choir to use to hold our music. They provide lots of room for a stack of papers and the clear plastic allows us to see what is in each pocket.
