Our book binder rings are the best binding rings on the market, made of a high quality metal that doesn't scratch or bend. Once closed, they have a tight bind that you can tug on and won't come open - this ensures your pages (or whatever is bound) won't fall apart. To open, just push the ring snaps apart and then pull. Binder rings are just as easy to open and edit, as they are to close and bind. Durable, affordable, and fun...it's no wonder why loose leaf rings are one of our most popular products.
