This is a melody mat featuring Wanwan from "Inai Inai Baa." It has scratches from children playing with it, and the material is prone to damage. There are also original creases, so please purchase only if you can accept these points. Playback is fine, with no sound distortion, and the sound is clear. The batteries have been removed. Also, it's worth noting that the mat is not in perfect tune. The original box states, "This is a toy, so the pitch is not exact. Please be aware of this beforehand" (see photo 9). Wanwan and U-tan are very cute. If you have a child who loves Wanwan, please consider it! NHK Inai Inai Baa Wanwan Wanwan U-tan Educational Toy Piano
