Thank you for viewing! This is a Holton practice mute for French horn (originally priced around 20,000 yen). There is some damage to the cork in one part (see photo 5), but otherwise, there are no noticeable scratches or damage. - Turning the dial in the center of the mute moves the three corks up and down (for fit adjustment). - The dial on the bottom rotates (pitch adjuster: I haven't confirmed if it works as I don't have a horn). I'm happy to provide additional photos and consider price negotiations, so please feel free to comment. I will ship it the same day as your purchase. Thank you!
