This is a practice mute for PIANISSIMO. Retail price: 4,950 yen. It has been used about 2-3 times and has been stored at home since then. As this is a used item, please refrain from purchasing if you are sensitive. It attaches to the bridge with internal magnets, so there is no worry of it loosening or falling off during practice. The entire mute is covered in rubber, so it will not damage the instrument or the bridge. It combines the advantages of both metal and rubber, resulting in minimal loss of sound quality and sufficient muting effect. Instead of covering the bridge from above, it is a wrap-around type, making the contact point between the bow and strings easy to see, and it is also recommended for beginners. The muting effect can be adjusted by changing the vertical position during attachment. It is very compact when folded.
