I like using the Mini Metal Binder Clips instead of the paper clips for my documents because if I need to photo copy the documents it is much smoother on the edges no wrinkles and it goes smoothly to my copier machine.
The very MINI binder clips are exactly what I wanted & ordered. They are very durable and they hold papers very well. My only personal challenge is because I keep my nails a bit long they are a slight challenge to open for the first time but that is not a challenge everyone will have. They are SMALL so they do not hold a lot of papers but I find these easier to deal with instead of paper clips that when flipping through things paper clips can pick up additional papers they should not. These binder clips work perfectly and hold only what I have put in the grouping.
