The Pearl Egg Carton features three egg shakers in a clear case that can be played separately or as a complete unit. Pearls egg carton is two percussion instruments in one: The whole egg carton can be played as a shaker inside the translucent case, or eggs can be removed and played individually. The carton has a series of sound holes at each end that focus the sound through the ends. These shakers can also be used as entertainment toys for Kids.
