The Clarke Kazoo is a quality product, featuring metal construction, a Natural Skin Membrane and durable color coat.
The Kazoo comes with an instruction sheet, and a tube shaped container for storage.
How to adjusting your kazoo:
The membrane holder is threaded so it can be turned clockwise to tighten the membrane or counterclockwise to loosen.
Start with the membrane holder just fingertip tight and, while humming into the kazoo, slightly tighten or loosen the holder until the loudest and cleanest sound is produced.
Now your kazoo is adjusted for your voice.
