This is a San-X product that I've kept at home but never used. It was in a clear case, so it's in very clean condition. (The case has some minor damage.) I inserted batteries to check its functionality before listing it. Both the microphone mode and the speaker mode work perfectly. In speaker mode, it dances to the music♪ It's hard to see in the photos, but the last three photos show it dancing♪ Thank you!
