I purchased this for a B♭ clarinet about a year ago, but it's been sitting around unused, so I'm putting it up for sale. The cork is in perfect condition. The bottom of the logo sticker is slightly scuffed, but this doesn't affect its use at all. It has very high muting performance and is lightweight, so it doesn't make the bell extremely heavy, and it feels good to play. I think it's a high-quality practice mute, and the original price of over 20,000 yen is understandable. A storage bag is also included.
