The outer cover is missing, and the author's name is written on the back cover (see the second image). Inside, there were some writings with a pencil, such as ○△, which I erased with an eraser (there might be some overlooked). Also, as shown in the 9th and 10th images, there are minor markings with a blue pen in two places. Other than the above, there are no folds or stains, and it is very clean. Please consider this after understanding the above. #Toshin High School #Toshin Books
