This is a used Demo of the Yonex EZone 100. It is a 4 3/8 grip size, and it's strung with a multifilament Synthetic Gut 16 at 52.5 lbs. Because its a Demo it has seen the court. On a scale of 1 - 10 this frame would be a strong 6. It has some minor scratches to the paint and scuffing to the bumper.
