Sponsors and Curators The Museum of Yo-Yo History is a labor of love, and we would not be able to stay up-to-date with exhibits without the support of our sponsors and curators. Big thanks go to One Drop Design and Duncan for supplying us with their latest models, YoYoExpert for their help and support, and to Cody Orr, TotalArtist and YoYoBrothers™ for allowing us to use their collections! If you're a manufacturer, or just a big collector and you want to help support the Museum drop me at line at chimera@yoyomuseum.com YongJun Crazy Bull Exhibit #2252 Type Production Shape Specialty Axle Bearing Packaging Poly Bagged Construction Composite Response O-ring Gap Fixed Condition Mint in Package Date 2014 Owner Rick Brough Compare 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.
