A Made in China ball bearing yo-yo that was sold in Japan. The package contained extra spacers and rubber o-rings: Type A (2 x 3.3 mm brass-colored spacers, 2 rubber o-rings,); Type B (2 x 3.5 mm steel-colored spacers, 2 rubber o-rings). The yo-yo is a knock-off of the Yomega Stealth.
Packaged with what appears to be 1 extra ball bearing, along with two sets of oxidized spacers, and 4 rubber o-rings.
This same company also made the ball bearing "Typhoon" yo-yo, a traditional shaped ball bearing yo also seen in this museum (not to be confused with Super Yo's "Typhoon".
Collected from the late Richard Williams, January 27 2006--a dear friend.
