What the plastic Imperial is to Duncan yo-yos, the Phantom is to BC/What's Next yo-yos--only in wooden form. The Phantom No. 21 was the first model in the Phantom series that went up to No. 24 over five years.
This yo-yo was a standard in the BC line-up and was marketed to hobbyists, professional yo-yo players, businesses, and universities. A three-piece maple yo-yo identical in shape to the Natural and Classic models.
