A collection of mystery novels by 4 authors, including Yasuo Uchida. This is a set of 30 books sold together. These were purchased new by myself and stored at home for a long time. While there are no major scratches or tears, there are various conditions, including many with yellowing and stains due to aging, and some that are relatively clean. Please check the photos before purchasing. Please note that we do not sell individual books from the set. We are sorry, but we cannot negotiate the price of this product. We may not respond to comments requesting price reductions because we are often unable to take the time to do so. Repeated requests for negotiation may result in being blocked, so please be aware of this.
