A Yomega Brain yo-yo sold under the Bandai America name. "Hyper Yo-Yo" is used on the packaging. This model uses an "X" configuration centrifugal clutch mechanism (in other words, it uses four bearings). Comes with extra string. The traditional Yomega Brain uses only two bearings in the clutch. The Australian Black Mamba uses three bearings. This is the butterfly version of the X-Brain. Collected February 6, 1999.
