The Mini Jam or Mini-Jam was the first undersized model by yoyojam in the late 1990's. A very early model, it had a lot of features common in the older jams. Small bearing axle with adjustable gap, composite construction, o-rings around the halves of the body for ground impacts. Also, no response system other than molding holes around the axle that acted as a weak starburst response. This one was a signature of Philip Travalent, at the time a boy that helped in the testing of the Mini.
Only one batch of these were released and then it was discontinued ... as the evolution of the yoyojam line continued.
