Kelly Mouthpieces are not only unique in their design but they also come in a vast array of unique colors. Made of Lexan material, the cup sizes are sampled by our professional staff and adjusted to produce our final, comfortable, easy-blowing mouthpieces. Our standard trumpet mouthpieces all have a larger throat diameter than their industry counterparts. Don't be another Trumpet player mixed in with the band. Stand out with your colored Kelly Mouthpiece!!
