Metal cone-shaped trumpet mute with cork end. This was a gift, but I already have one I use, so I'm giving this one away. Selling price: 3230 yen This trumpet mute is perfect for nighttime practice or practicing at home, with excellent sound reduction! It's small, so it can be stored in the case while attached. It can reduce the volume by about half. *Please be careful not to push it in too hard when attaching it, as it may become difficult to remove. Product number: ktmt02
