Osaka University Science Departments (Science, Medicine, Dentistry, Pharmacy, Engineering, and Engineering Science) 2023 Edition Edited by Kyogakusha Editorial Department Price: ¥2100 There are pen markings on the problems, as shown in the photos on pages 3-5 (mathematics, chemistry, and physics pages), but I think the markings do not interfere with solving the problems. Other than the markings, the overall condition is good and I think it is clean. #KyogakushaEditorialDepartment #Books #Others/Others
