Kotaro Isaka paperback book set for sale I received these from a friend who loves Kotaro Isaka, saying they're interesting and that I should read them! However, I haven't had a chance to read them, so I'm putting them up for sale. Most of them were purchased at used bookstores many years ago. Therefore, there are various signs of wear and tear, such as stains, folds, scratches, and price markings, in addition to what's shown in the photos. They are not in very good condition. Please understand this before purchasing. I plan to put all the books together in a plastic bag, wrap them in bubble wrap, and ship them.
