I used this a bit during the entrance exams, but as far as I could tell, there were no noticeable stains or folds. I apologize if I missed anything. It can be used for the Common Test and second-stage exams. Instant purchase is OK. Price reduction is OK. If you have any questions, please comment! I am also selling other reference books! → #melon reference books You can see them here ^^ Regular price: 1000 yen + tax Common Test Ethics Politics and Economics Politics Economics Question and Answer Toshin
