The quality is decent and there is handy information on the inside covers. The pages are securely sewn in. The cover is not as sturdy as I would like--it bends easily.
I love these have been using these for many years. Before this purchase they were sold at 50 cents each so I stocked up on them in bulk by the box. I only use one side of the page as I don't even want a hint of ghosting when copying a page. I highly recommend.
