This yo-yo was a prize for completing a series of tricks in the Yomega Pro Spinner program, late 1990's. At the time, it was only available as a prize. However, a store on the Internet began selling them to the public.
This is a Yomega Fireball yo-yo with the Pro Spinner logo imprinted on the sidecaps. The yo was sold only in a polybag with no header card.
