60 Srixon Q-Star Yellow Golf Balls 5A Grade Mint Grade (AAAAA): Almost new, with very few visible signs of wear. Like a ball that has been hit a few times. Still guaranteed to perform like new. Player pen markings and logos can be present. The Q-STAR is for golfers who demand premium performance in an all-ability golf ball. Engineered with tour ball technology, the Q-STAR delivers a superior combination of distance, accuracy, greenside spin and durability. SECOND GENERATION SPINSKIN The new coating increases the frictional force at impact by 18% compared to the previous version resulting in even more greenside spin, control, and a softer feeling ball. 324 SPEED DIMPLE PATTERN Next generation Speed Dimple technology combines higher dimple uniformity and surface coverage to create a more aerodynamic design with less drag, resulting in longer distance and a truer ball flight in any wind condition. ENERGETIC GRADIENT GROWTH CORE Advanced construction optimizes S.T.A.R. Performance. (Spin, Trajectory, Acceleration, and Responsiveness)
