This item for sale is a Vincent Herring custom mouthpiece made by Ken Okutsu. It is an alto saxophone mouthpiece. This mouthpiece is famous for being used by Vincent Herring and Elena Terakubo. Unfortunately, Mr. Okutsu has recently been in poor health and is no longer taking reservations, and there is no prospect of a restart, making this mouthpiece very rare nowadays. Those looking for one should purchase it as soon as possible. Recently, there have been many cases of product substitution, so basically, no returns or exchanges are accepted. - Brand: Ken Okutsu - Model: Vincent Herring Custom Model - Country of Manufacture: Japan - Accessories: Box Thank you for viewing.
