GOSEN 17 Tennis Black G-SPIN3 String, TSGS31,

Gauge: 17/1.23mm (min 1.19mm - max 1.27mm) Length: 12.2m (40ft.) Suitable tension: 45-55 lbs Color: Crimson Red/Black Country of manufacture: Japan To "win," you need the "sensation" at impact plus the "spin" to control it. By giving the G-TOUR3 a polygonal shape, the "feel" at impact (a gripping feel of the ball combined with optimal resilience) is enhanced with an added grip on the ball, creating the "spin" needed to push the ball deep into the opponent's court and dominate, helping to "win."
