Haiabei 54 Pcs Plastic Multi-Color Book Rings Loose Paper Leaf Binder Rings for Coil Paper Cards Photo Album Menu Book,Assorted Sizes

I found these easier to handle than the more common metal variety. The biggest reason is probably the fact that the metal kind have a hinge, which is either too tight or too loose. When a metal ring is open, it will tend to come further open, spilling your cards everywhere. So you have to keep a close eye on it. The plastic ring is elastic, so it wants to close, which is better.The plastic clasp is a little hard to open and close the first few times but quickly softens up to a comfortable hold. So far none have opened accidentally.

These are pretty small, so they won’t work for my project.

Love these. Wish I could buy the smallest size by itself though.

I use these all the time. Lightweight and durable.
