GOTOONE Book Binder Rings 2 Inch Office Loose Leaf Ring（20 Pack） Nickel Plated Silver . This is a great set of all-purpose binder rings. They fasten easily and hold a good quantity of papers. I'm using them for more than loose paper management they're also useful for keeping other items together, like ponytail holders and measuring spoons. I'm very pleased with these for functionality,sturdiness, and value. I got them they were all great, no rust, and snap tight. I will definately recommend to friends and family.
