This clever little crankshaft music box will delight you with its lilting version of 'What a Wonderful World'. Forget the MP3 player - here's music in your hand old-school style. The tune will continue to play for as long as you keep crank the handle. A great gift for fans of the lovely Louis Armstrong. Hand-crank music box measures 1 1/2" x 1 3/4" x 3/4". Remove from the presentation packaging and place on a flat surface to hear fuller sound. Feeling creative? Craft your own music box with this for the mechanism.
