The MiniJam was YoYoJam's first miniature yo-yo, released in 2001 as the signature series model. Similar to the SpinFaktor, it is a composite-material yo-yo, made of plastic with metal rims and O-rings. It has no response system, relying on the molding dimples on the inner surfaces around the area of the bearing. Because it is similar in size to the metal hub of the Henrys Viper, it can be fitted with Viper shells (see Gallery below).
- The MiniJam is one of the smallest production yo-yos, smaller than even the MicroMo and the Tom Kuhn Pocket Rocket, but not as small as the Yoyomonster 3Points or the YoYoFactory Mighty Flea.
