Decent condition, there is some pen writing on the cover and inside in a few places, but nothing that makes it unreadable. There's also a little bit of markings/dirt on the back cover that didn't seem to come off when I tried to clean it, so I'd say the condition is fair to low good, but not great. Please see all photos for details. The photos are of the actual item you will receive.
