This is a U-Can Interior Coordinator course purchased in June 2020. I believe it cost around 50,000 yen. There are writings, markings, and stains in various places in the texts. There are no missing pages, so it should be usable. There are many writings and markings. It is a complete set of everything sent by U-Can.
