The Mosquito is Duncan's first miniature ball-bearing yo-yo. It was designed with a price point in mind of under $10. The body featured a translucent plastic with opaque non-removable caps in the initial versions. Later versions feature removable caps, held in place by screws. Featuring friction stickers with a small starburst response underneath it, allowing for a combination of response types.
