Metal mouthpiece made by PERANTUCCI, featuring a circular design for high responsiveness. - Brand: PERANTUCCI - Model: Mouthpiece - Material: Metal - Shape: Circular Purchased approximately 15 years ago, it has scratches and dirt commensurate with its age. The opening of the box is torn and missing. The mouthpiece itself is still usable, so how about it for equipment in general wind bands or school bands?
