This yo-yo also goes by the name of "Fin Hop Jet Fire" which came in a large display box. The version in this exhibit is identical but packaged in a small, sealed plastic bag instead.
The Crazy Bull is somewhat similar to the ProYo Mongoose, in concept. This version came with the core and three different sized body shells for customizing the play and feel of the yo-yo.
Came with three different sized body shells, one aluminum core that works on each set of body shells, three o-rings for the response systems on the shells, one C size bearing, and string.
