I have been buying these type of Binders for a few years now. I love them because they are sturdy and stylish. Most of my engineering notes are protected in these types of Binders.
It's cute. It just isn't roomy enough for all of my daughter's subjects and she isn't crazy about how the binder slopes allowing her things to fall out.
I love these binders. they last a long time and they don't split at the seams - due to their fabulous construction. They can handle a lot of opening and closing of the rings and the prongs continually line up.
