This is a complete set of volumes 1-17 of Ajin. No individual sales. After purchasing from a bookstore, I read them a few times and stored them on a bookshelf. All volumes except for volume 1 are first editions, and there are no noticeable scratches or stains throughout the set. There is almost no yellowing, and I think they are in beautiful condition. The advertisements that were inserted in the books at the time of purchase are also included.
