The only problem we had was getting these sheet protectors to "open up" so we could put the sheets in them. Almost as though it was stuck together. Spent more time getting them "opened up" than anything else.
We used these to put signs in for a recent fundraising event. You can cut off the part that makes them able to fit in to a 3 ring binder. They are sturdy durable and a great price for what you get. I loved them!
