The GOSEN Polylon series boasts the world's first and only string with a geometric-shaped design. Since its launch in 2010, the series has seen a steady increase in shipments each year. Among players ranging from their teenagers to seniors, SIDEWINDER is the most popular polyester string. Its elliptical shape and uneven processing contribute to its high resilience, soft feel, and exceptional spin.
