Fabulous binder rings. I will be using them for personal gifts to bind paper crafted homemade mini albums. A perfect size that allows the pages to turn freely. They are tough and very durable. In the past I used them to hold a tiny booklet of post it notes to the outside of my purse. The booklet fell apart but the ring did not waiver. If the rings can endure living on the outside of a busy purse you know they are tough. LOL great product! =D
