This is a tuner that my daughter used in the wind instrument club for about six months. I've confirmed that it works fine with batteries inserted. (Batteries will be shipped separately.) There are some scratches. I tried to remove a sticker that was used as a marker with nail polish remover, and the "YAMAHA" lettering in the lower left corner also came off... I will ship via Yu-Yu Mercari. #WindInstrumentClub #WindBand #Yamaha
