I had to return them to the store. They are so tight I could barely get an 8.5 inch piece of paper into the protector. I tried all sorts of tricks to prevent damage to my pages and finally tired of the effort. Note to the manufacturer: if you expect us to slide in 8.5" wide paper you may want to provide more than a tiny fraction of a millimeter for extra width!
The quality of the protects is very good. I spent too much time putting things into the protectors. They did not open easily and if I placed more than a couple sheets in a protector they didn't go in smoothly.. The protects need to be a hair bit wider to make it easier to use.
