This is a used item that my child used while attending Mabuchi Kyōshitsu. There are no writings or stains. Mabuchi Kyōshitsu Junior High School Entrance Exam Course: Japanese 6th Grade N Class: Japanese Vocabulary for Nada Junior High School Entrance Exam Day 1 Summer Seminar Self-Study Assignments Combined Volumes 1-24 With answer key and explanations There are quite a few pages, and it took a while to complete. I think it's better to start working on it early. Thank you for looking.
