This is a ligature for a tenor saxophone, made by Bay. It's for hard rubber mouthpieces and is gold-plated. Bay ligatures have a delicate and beautiful pattern, making for a very exciting design. I think it will also make it easier to produce sound. The craftsmanship is truly delicate, so I will include a Yamaha 4C tenor mouthpiece for you to set it up with. The mouthpiece is also practical and usable. It will be sent via anonymous delivery, Takkyubin Compact. This item sells for around 13,000 yen.
