The Master is one of the finest Diabolos on the market. Designed by and for diabolo players. It features full sized cups made for an ultra tough and transparent polycarbonate plastic embossed with four site lines and the Zeekio logo. These cups maintain their shape well and look great. This triple ball bearing version comes with three high speed steel bearings. One ball bearing set on each end of the axle, and the axle itself is seated on a needle bearing that is between the axle and axle sleeve. This enable insane spin times and some seriously fast revolutions. Spin Master's wide axle is "v" shaped to draw the string to its center for the least amount of friction and longest possible spins.
