At the time, this yo-yo was a new concept from YoYoJam--a new yo-yo company on the scene. A bearing yo-yo with a rubber outside cast over a hard plastic internal system. The rubber is soft enough to give a bit in the hand, but is clear of the string's track so as not to slow it down. Designed for looping.
After more than 16 years, Yo-Yo Jam officially closed its doors and went out of business Wednesday, December 30, 2015.
