Comments about Fellowes� Premier Flex Arm Copyholders; Weighted Base Model:
While I have used these dividers in a binder, and liked them, I am using the ones I just purchased for something completely different. I love to do Sudoku. If you enjoy doing them yourself, you know that the paper in those books is soft, so the impression goes through the pages as one writes. By inserting one of these dividers under the page one is working on, you have a firmer surface to write on. I also fasten each Sudoku book into a clipboard, which holds the pages open and makes a good surface while writing.
