The Trumpet Kazoo is a kazoo with a bell and valves(which do work, although not affecting the sound). You play it like any kazoo--by humming the tune into the mouthpiece. It is 11 inches long and made of metal with a plastic mouthpiece. This is a great novelty item made in USA by the only company in the world that makes metal kazoos. It is not recommended for children under 3.
