This entire range of quality brass mutes are a must for any gigging amateur or pro!

They are made from a strong polycarbonate material and can sustain the hardest of knocks, ,according to the manufacturer, they are "indestructible". The sound they produce is extremely good and clean and can compete directly with more expensive brands. Several of my brass-playing colleagues (and myself) have tested these and were thrilled with the tone and how easy they were to play with!
