Fun Express - AZ920 (48 pieces), (2.5 inches) Plastic Mustache Lip Whistles - Small Party Whistle (Black)
When you blow this cool Mustache Whistle a small wheel spins to create its unique whistle sound (similar to that of a Kazoo). These whistles are made from a heavy-duty plastic. A whistle is a simple instrument which produces sound from a stream of forced air.
