I purchased this about six months ago and used it for about three months. I am now selling it because I am using a new mouthpiece. I selected this one from over a dozen at a musical instrument store because it had good articulation and made expression easy. The patch is still attached, so please discard it if you don't need it. (The patch was only used for about three days after being replaced.) I will pack and ship it in the original box. ↓ The following is a quote from the product description: The tip opening is between a 5RV Lyre and an M30, offering a moderate playing feel that isn't too hard. The facing that meets the reed is long, providing high flexibility, and it works well with harder reeds. This mouthpiece produces the core, mellow sound characteristic of the M30, making it easy to play and well-balanced. It is especially recommended for players with some playing experience.
