I purchased this about two years ago and used it while making copies. I checked for writing and found none. However, since it was a layman's check, there may be oversights, so please understand. There is some creasing on the cover, but I think there is no problem using it, so I am waiting for your purchase if you don't mind. I do not offer discounts. Also, I do not hold items. Thank you for your understanding.
