ULTRA USA Silencer, Rubber For fractional violins (1/16 to 1/4 size) This is a silencer (mute) that a child used. It was used to reduce the sound during nighttime practice or when practicing away from home. It wasn't used very often, but there are some minor scratches from when it was new. Thank you for your understanding if you are purchasing a used item. #Silencer #Mute
