Taan TS5600 tennis string reel 200m/660ft. The string is made of advanced co-polyester. The thickness is 1.15mm or 18 gauge. It actually has good durability despite the thinner gauge. However, because the power and flexibility of this fusion polyester string is comparable to the Babolat RPM Blast and Luxilon ALU Power, those with arm issues should not buy this string, string at lower tension, or hybrid it with a softer string.
