I just quit buying any other binder. These are perfect multiple sizes and colors and I haven't worn one out yet. My granddaughter did ruin one getting it shut in a slammed van door . . .
I was disappointed not to find any soft-cover binders that would suit my needs. Also the shiny plastic sleeve on the front cover and spine were very hard to remove and I needed the folder to be plain black and not shiny. I did use the folder bur suggest you look into locating a source for sturdy binders with inside pockets and a soft cover.
