Please check my profile. Prefecture Learning Flashcards Teikoku Shoin These are flashcards that help you learn the shapes of the 47 prefectures.

A4 size, made of sturdy thick paper. The corners are rounded to prevent injury. In the second photo, there is a mark where a sticker was removed from the storage case. Thank you.
