Avery Reinforcement Labels are great for reinforcing hole punched sheets of paper that are put in a binder. I don't remember what I paid for them, but I know they are relatively inexpensive.
I usually get the clear, so they don't cover up any writing or typing that might be on the paper. They also come in white. There are 200 labels to a box, and they are self-adhesive. Once you put them on the sheet of paper, you can bet they will stay on.
I've had unreinforced pages in a binder start to rip at the holes, and an Avery Reinforcement Label takes care of the problem. The only downside is that if you reinforce each page with these labels, it does increase the thickness of the pages, so that you won't be able to put as many pages in the binder. To prevent this from happening, I usually just reinforce the pages that need it.
I would recommend Avery Reinforcement Labels. They certainly do help to keep binder pages intact.
