Rolling Flinger

Three 16mm marbles loosely held in a plastic casing with a finger flinger on one end. 

Can be used one-handed (rolling and flipping with the marbles using thumb and fingers, a finger can be inserted into the flinger ring and the device twirled whimsically around in the air) or two-handed (rolling the marbles between the palms),. 

Approximate size: 4” x 1”/1.5” (column/ring)
