This is a KUMON clock learning card set. It supports both English and Japanese. There are 46 cards. All cards have punch reinforcement stickers applied to prevent tearing. They are organized with rings for easy (o'clock, half past o'clock) and advanced learning, allowing for learning while flipping through them. If you don't need the rings, please let me know via the transaction screen. There is no box, so we appreciate your understanding. I am also selling the KUMON Kurukuru Lesson (for clock learning).
