"Basic Science Problems for Junior High School Entrance Exams, 5th Grade" Nichinoken Teaching Department Price: ¥900 I would like the set of Math and Science. The math book has writing on 3 pages as shown in the photos, so I've marked it as having scratches and stains, but there are no noticeable stains on the other pages. The science book is unused. I have checked carefully, but please forgive any oversight. #NichinokenTeachingDepartment #Book #Nature/General"
