This is a multi-functional educational toy that provides a learning experience. Perfect for preparing for kindergarten, elementary school, and the next grade level! Suitable for children in kindergarten and daycare! Also great before and after entering elementary school! The card game seems to be for around 2nd and 3rd graders. The battery compartment requires a screwdriver to open, so it's safe. (Except for the white one) Operation confirmed. Batteries have been removed. Button batteries are still inside. (For size confirmation) No instruction manual. Since everyone's perception of condition varies, please check the photos. Stored at home. Please understand and purchase. I believe it can still be useful. Thank you for looking. Type: Words/Language Popular Keywords: Kodomo Challenge
