This is a tuba mouthpiece (VINCENT BACH 18). It produces sound, but as a novice, I can't judge its quality. Why not consider purchasing it for practice? The tip is warped due to being dropped in the past. There is also some staining as shown in the image. Please purchase only if you don't mind these imperfections. It has been carefully stored by a novice in a shelf in a dark place. Please be aware of this if you are particularly sensitive or a perfectionist. Instant purchase is welcome. Please feel free to ask any questions or make inquiries about price negotiations or other matters.
