Designed by World Champion and yo-yo legend Shingo Terada, this weight is the real deal. Through exhaustive experimentation with various plastics, we arrived at the perfect material for this design. The Candy Dice is engineered to perfection; excellent maneuverability, fast spinning, and the convenience of easily attaching the weight to the string are only some of the factors that make this weight great. So put the string in the groove and play!
