Showa University School of Dentistry Tokyo Dental University Nippon Dental University Osaka Dental University This is a set of 4 "Akahon" (red book) past exam question books. The Showa University book has some writing in it, and the back cover has a crease. The others are in good condition. Ideal for those who need past exam questions, covering 5-10 years' worth. 3800 yen per book Total: 15,200 yen, so I think it's quite a bargain. For those who understand that these are used books. Thank you for looking.
