Used but not abused. These books are good condition. The covers show little wear. The upper layer of the cover on the book spine is separating on Spore (shown in photos), but other than that, these books are free of rips & tears. The page edges of all four books have some spots of discoloration. I am not sure what it is. There are a couple spots of discoloration on the book pages themselves, as noted in the photos. I didn't flip through every page, but the number of spots appear to be limited.
