Used by ATP Tour professionals, the Luxilon Original string provides amazing control, massive spin, and outstanding durability. Combines plenty of bite and control but still plays softer than most traditional monfilaments while offering outstanding tension holding ability. Player with high-head speed will notice a quick snap-back for added power and a heavier spun ball.  Composition: Co-polymer with Fluocarbon resin Gauge: 16 / 1.30mm Color: Amber Length: 40ft / 12.2m
