These plastic covers (binders) are thick and sturdy and clear enough to see the cover page through the front. The main (totally terrific) feature is the well-made clamp inside that lets you insert up to about 100 pages WITHOUT PUNCHING ANY HOLES and almost instantly securely fasten them in or open the clamp for access to any or all the contents without unthreading them from any poles or rings. This lets you gather sheets that are printed very near the edges without having to destroy any parts of them with punched holes. I highly recommend these covers. I ordered by mail and got my order the next day! Well done Staples!!
I really like these binders because they can hold a lot of pages. Most binders have a limit as to how many pages they can hold. They are also have a very professional appearance.
