I purchased this item, but I haven't used it much because I already had the same reference book at home. It has been stored at home, so there may be minor scratches or stains. No writing. No folds. No yellowing. This book, "Kiso Mondai Seiko," covers from basic to standard levels and can be used for preparation for university entrance exams. The explanations are thorough and easy to understand. You can purchase this item immediately. Retail price: 1650 yen Thank you for looking.
