Okura Mute for Tenor Trombone Purchased new about 10 years ago, this mute has been a great help during practice sessions when I couldn't make loud noises ♫ (It cost about 5,000 yen). I'm selling it because I bought a new practice mute and no longer use this one. It not only silences the sound well, but it also doesn't feel bad to play, and it's light. Plus, when you put the instrument in its case, you can store the mute inside the bell of the instrument, making it easy to carry the case around. There is some deterioration from years of use. I don't think it affects the use, but if you're concerned, I can add more photos, so please comment. If you want to practice your trombone properly at home, please consider this!
