Alto Saxophone Mouthpiece: D'Addario Reserve This mouthpiece has been stored with almost no use, so there is no wear on the table or rails, and it is generally glossy and in beautiful condition. If you are looking for one in good condition, please consider it. - From the Selmer website - The metal ring and cut design, which are characteristics of Adolphe Sax's first mouthpieces, are based on the traditions and know-how gained from the development of the Concept series, and are completed as a "hybrid of ebonite and metal" mouthpiece. The gold-plated metal ring covers the entire bore, enhancing the sound's projection and providing a more detailed and rich sound. * To prevent replacement, returns are not accepted.
