"Ibaraki Prefecture Public High School 6-Year Super Past Papers" Price: ¥1100 My child used this for their entrance exams. There is a slight fold on the corner of the cover. I checked inside and it seems there are no markings. I also confirmed with the user (my child), and they said there were no markings. (There might be something I missed) I would appreciate it if those who understand that my child used this would purchase it. As a side note, they passed the prefectural high school entrance exam. Thank you. #book"
