This is an original mute from Juso-do Gakki, a specialist in selling high-quality, authentic erhu. The material appears to be ebony, with a good texture and a luxurious feel. It's a rare, discontinued item. How about it if you're looking for one? The 6th photo shows it attached. - Material: Wood - Color: Black - Shape: Rectangular Thank you for looking. #JusoDo #Erhu #Mute #Mute #Ebony
