Retail price: Approximately 46,000 yen This is a mouthpiece that is rarely available in Japan. It's a handmade mouthpiece by Arnold Montgomery, and each one has a very high quality. This model, ARAS, was designed with Berg Larsen in mind, and features a bullet chamber. The material is ULTEM resin, which is highly durable. Also, there is a metal ring on the shank, and I feel that it allows for a wider range of overtones. I contacted the maker directly and imported it from overseas, so it's very valuable. Thank you. Below is a translation of the official HP description: Aras is a modern-sounding mouthpiece with a high baffle and bullet chamber. It has an edgy, thick, powerful, and focused tone, and is perfect for funk, blues, Latin, and jazz. #alto sax #mouthpiece #jazz #funk
