Griego NY Model Large Shank 0.25 Silver Plated SP Rim Diameter: 29.39mm Throat: 8.08mm ★This item was purchased from a professional musician and has been test-played a few times. * There are scratches and corrosion on the shank due to use, but there are no problems with attachment. * This is an old model and the case is plastic. 【 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, and while it has the capacity to handle large volumes without breaking down, it still maintains control. This model is suitable for those who want a powerful, large size.
