Kellogg's Attack Rings
Kellogg's Attack Rings were promotional items given out in Kellogg's cereal boxes along with a hand-spinner "base" which came in the same colours as the ARs but were apparently randomly combined with each of the ARs. These did not use Weight Discs and did not have grooves for Left-Spin Spin Gears (though being hand-spun, they could be used in any direction stock). The colours shown below were released in the UK and Australia, while translucent versions were released in Germany and possibly other EU Countries.
