They are perfect for three hole punched pages.

The top 10-20 were clear with holes on the edge, not requiring me to punch holes in the actual document, which was what I had thought I had purchased based on the advertisement on amazon

To use, you must punch holes in your 8 1/2 x 11 inch paper, place it into the opened sheet protector, and the protector lays down and folds over the inner hole-punched edge of the black paper to close around the underside of the inserted sheet.

Very heavy, sturdy pages & glad to see the holes are pre-punched
