The X-Con was a long lived model from Yoyojam, the signature model of Johnnie Del Valle. Adjustable string gap, Half Spec C bearing axle, hybrid body, double O-Ring response, and optimized weight rings on the outer rims for maximum spin. I think this one was released about 2006 to 2007. The color is a pearlescent lime green with matching sides. Hard to see, but frosty lime color and sparkly.
