The guides are in varying conditions. Most of them do have some sort of wear/tear to the corners and along the edges. Some have some slight rips. Below I have listed specific issues with each book. I've done my best to list out most issues and have the condition of each pictured, but can send more pictures if you need as I've reached the max. Just note none of the books are in perfect shape.
