Plastic kazoo, 4-3/4" long. Colors will vary, and may include pink, green, yellow, or orange. What makes our kazoo different? The West Music Kazoo is manufactured with the highest-quality plastics (polypropylene) and pigments. They are molded in a state-of-the-art, medical quality injection molding facility in the United States. Cheaper, imported kazoos are made of polystyrene, which is brittle and breaks easily leaving sharp edges. Our kazoos are not brittle and do not break. It"s all about the resonator...that little round paper underneath the "child-safe" cap is what makes a kazoo work. Many kazoo manufacturers use cheap wax paper or cellophane to make the resonator. The West Music kazoos are made with a high-tech polyethylene paper that is louder and longer lasting than most kazoos. Best of all, our kazoos are waterproof! Our manufacturer has their own custom-built resonator cutting machine that creates the resonators to their exact tolerance. The resonator IS the kazoo! It"s all about safety! Our manufacturer has spent thousands of dollars on improvements to their tooling to ensure that our caps are not easily removeable and are safe for kids! The West Music Kazoo caps are inserted by a machine with 100 lbs. of pressure. Our cap cannot be easily pried out.
