The rings on this binder did not close properly and papers would get stuck on the points tearing them. I exchanged it for another one and the same thing happened. My child`s teacher said that this particular binder had issues with the rings and to purchase something different. My child chose this binder because of the rounded spine making it easier and more comfortable to carry which was a definite plus. We could not find any other binders with the rounded spine. It was unfortunate that the rings did not close properly.
This is the only binder I've found which lasts longer than a few weeks in use by my middle-school son. The other binders rip at the seams and the rings fail.
