*Raw brass, polished brass, and unlacquered instruments and mouthpieces will tarnish quickly and may not arrive with a flawless finish. This is a natural property of raw brass, which will develop a rich golden-brown patina over time.
California residents: See Prop 65 warning.
All brass instruments and brass instrument mouthpieces may contain lead, which is known to cause cancer and reproductive harm. – www.P65Warnings.ca.gov
