I purchased this, but I've finished using it, so I'm offering it to someone who can use it. There were original date writings, but I erased them with an eraser so they're not noticeable. There are some signs of use on the back cover of the problem book and the back cover of the answer book, but the inside is clean. Please refrain from purchasing if you are concerned. This is an arithmetic problem book specifically for junior high school entrance exams, containing the highest level problems. - Title: Junior High School Entrance Exam Highest Level Problem Collection Arithmetic - ISBN: 9784757651585 - Author: Hideshi Kurine - Publisher: Bun'eido - Language: Japanese #JuniorHighSchoolEntranceExam #EntranceExam #Arithmetic #ReferenceBook Thank you for viewing.
