Thank you for looking. My child used this a little. There are creases on the cover. I believe there is no writing inside, but please forgive me if I have overlooked anything. Other than that, there are no tears or noticeable stains/scratches, but there is some deterioration due to long-term storage at home, so I would appreciate it if you could understand. - Title: Arithmetic Plus One Problem Collection - Author: Toshiaki Mochizuki - Target Grade Level: Elementary School / Junior High School Entrance Exams - Publisher: Tokyo Shuppan
