This FreeHand Zero was released to commemorate the event, and sold only at the 2004 World Contest. Only 300 were made, but extra side caps were also produced and sold. So other FreeHand Zero colors with this side cap may appear from time to time, as well as extra unused side caps.
Like most collectibles, yo-yos are worth more and are more desireable to collectors if they are still sealed in the original packages. That is why this one is pictured though the package bubble.
