Griego NY Model Large Shank 0.25 Gold Plated GP Rim Diameter: 29.39mm Throat: 8.08mm This item was purchased used and has been test-played a few times. *Cosmetic box/case not included. There are no noticeable scratches or accident history, and it is in relatively good condition for a used item. There is a very slight peeling of the gold plating, but it is within a range that does not affect the quality or performance. 【 New York Model 】 This is a standard-shaped mouthpiece, but it is designed to be slightly heavier than current Bach mouthpieces. The 0.25 is the largest size in the lineup, but it is not too heavy and is relatively easy to control.
