Thank you for viewing! Kodomo Challenge English Edutoy Talkeyboard I haven't used it much and have stored it at home. There are 8 cards that can be used on both sides. It has been disinfected. I will ship it with new batteries installed. Operation has been confirmed as of August 2025. *Please note that we cannot guarantee any malfunctions after that date. We are looking forward to your purchase if you understand that this is a personal inspection. Immediate purchase is welcome. When you press the keyboard without inserting a card, the Do Re Mi Fa So La Ti Do sounds will play. When you insert a card, English songs and quizzes will play, allowing you to study English.
