Rim Inner Diameter: 25.73mm Throat Diameter: 6.87mm Weight: 125g This is a Denis Wick trombone mouthpiece 5BS for small shank trombones (silver-plated). Compared to the Bach 5GS, it has a slightly deeper cup and a more defined shoulder, giving it a rich sound with brightness and brilliance, making it a truly all-around model. Furthermore, the relatively flat rim with a clear bite feels comfortable on the mouth and provides a fast response. [Condition] ・Minor dents on the shank and slight scratches from use (photo 6) ・Minor dents on the rim, barely visible in the photos (photo 7) ・Minor dents on the shank, barely visible in the photos (photo 8) Other scratches from use are present, but the plating is intact, there is no distortion, and it can be used without any problems. This item does not come with a box. As a bonus, I will include an original trumpet station cloth. This is a used item, so please refrain from purchasing if you are sensitive to such things.
