Ellery Queen Sogen Mystery Library Hayakawa Mystery Bunko Kadokawa Bunko 23-book set in total List price: 24,780 yen (excluding tax) All purchased new from bookstores last year. Some covers show slight dirt or scratches, but there are no stains or tears, and they are in good condition. Instant purchase available. Individual sales also available (from 700 yen/book), but I'd prefer to sell them all together, so I'd appreciate it if you would consider purchasing them as a set.
