This is a classic jazz mouthpiece, the "Meyer 5MM (for alto saxophone)." According to the previous owner, "I purchased this as a new, selected item from Ishimori Wind Instruments about 4 years ago. It was a selected item by Wataru Hamazaki, but I've lost the selection data card. I used it for about half a year." Therefore, there is nothing to prove the selection, but in my opinion, it was easy to control and I felt it was a selected item. I used it for about 2 months. It's in relatively clean condition, but there are some scratches and signs of use. It comes with the box and ligature, so please check the photos. I really liked it, but I believe in "selling off what I buy," so I am listing it this time. Please understand that this is a used item and that individual perceptions may vary. Please purchase with no returns or exchanges.
