This is a set of Shin Chugaku Mondai-Shu (New Junior High School Problem Collection) - Advanced Edition, including Math and English. The Math book has some writing on the angle pages, which has been erased with an eraser. I have included photos of this. There is only one page, I believe, where a mark could not be erased. Please check the photos. The English book has check marks next to the vocabulary words, which have been erased. The answer booklet shows more signs of use. The Math book has a torn corner. Please check the photos. I apologize if I have overlooked anything. I believe these books can still be used. I would appreciate it if you could understand that these are used books. Thank you for looking.
