These are very useful for the genealogy documents I prepare. Some are over one hundred pages long. I used to buy them in the store but must order them online now. I would recommend
The binders work just fine just what I needed for hundreds of pages that are not 3-hole punched. What is annoying is that they are not sold in my local Staples stores. They have thousands of 3-ring binders on the shelves and no clamp binders so the latter have to be ordered on-line.
