The Giant Cosmic Spinner is larger than most tops and is what's known as a palm top. While you can spin it with your fingers, for longer spins you spin the stem between the palms of your hands. It is made of wood and laser cut into an eye-catching purple spiral. Since portions are cut out, when it's spinning you can see through the top. Because of it's large diameter, it's very stable and can even spin on your hand. Toycrafter, the company that makes these, has gone out of business. When these are sold out they will not be available for sale again. Diameter = 9 inches (228 mm), Height= 3 1/4 inches (82 mm).
