This is a kanji book my younger sister bought a long time ago. The cover is stapled on so it won't come off. There are no noticeable writings or major scratches. Red sheet is not included. *This is the 2012 edition, so it's old. Please use it more for kanji practice and checking your kanji proficiency rather than for trend analysis and test preparation. No claims and no returns, please. "Frequently Appearing Kanji Test Level 6 Problem Collection" Seibido Publishing Editorial Department #SeibidoPublishingEditorialDepartment #book #language/Japanese
