We had a terrible time for years finding a binder that would stand up to school. We would go throug a binder each making period. The binders we bought were not tough enough to stand up to everyday school activity. When we started using this binder that all changed. No more rings opening and papers falling out. No more covers coming off. No more breaking when someone knocked the binder out of your arms. This is the only binder we buy now. It is the best. The recycle program makes buying this binder even better we get a little off turning in the old when we buy the new.
I use these binders for organizing my course work for graduate scghool. The 3" size is perfect and durablef although it is a larger binder. Flexible covers allow for opening binder and folding under. Also binders come in great colors. I also use them at work to store documents etc.
