The Remnant is String Theory Yoyo's first release and we are pulling out all the stops. We had it precision machined for maximum stability. We included a Dif-E-Yo KonKave bearing to center your string for a perfect throw everytime. It has a balanced rim weighted design to maximize spin time and stability. And lastly we have tested it extensively to ensure quality. Pick one up and see what happens when a yoyo is designed by yoyoers.
