This is a set of three lightweight polyester plastic mutes for trumpet. By P&H London, this set includes a straight mute, cup mute, and Harmon-style wah-wah mute, which will set you up for most any playing situation. Packed in an attractive display box, it's the perfect gift for the stopthatpracticing! beloved trumpeter in your life. The large red labels stick only partially to the mutes, so they'll likely be unlabeled once you use them a bit.
