Metal French horn mouthpiece, used condition. - Type: French horn mouthpiece - Material: Metal - Condition: Used Thank you for viewing. This was purchased 3 years ago at YAMAHA for my child to use in their club activities. (I consulted with a salesperson and they recommended this as suitable for beginners.) It has been left untouched since they retired, so I am selling it at a low price as I haven't maintained it.
