Lab testing shows exceptional performance, combining high spin generation with reduced stiffness for enhanced feel and playability. Featuring a hexagonal profile for maximum bite on the ball, O-Toro is available in 1.23mm (17) gauge across multiple color options. Each package includes two half sets (6.7m each), providing enough string for one full racquet.
