With a turn of the elegantly shaped key, "Voi Che Sapete," from Mozart's The Marriage of Figaro, emanates from inside of this wooden ball. The 18-note chime plays whether it is rolling across the floor or decoratively resting on its small metal ring. It is made of premium quality oak wood that has been fashioned into a perfect sphere by village craftsmen on the edge of Germany's Black Forest. Not for children under 3.
