  BOWLING BALL.......This ball is a  factory second because of A tiny scratch that was already repaired at the factory....PICS ARE OF THE EXACT BALL LISTED..

The Hammer Maximum Effect is the most aggressive and high-performance ball in the popular Effect line. Built for serious traction and control on medium to heavy oil conditions, this ball delivers the signature Effect motion you love—but turned up to the max. For the first time, Hammer has paired their proven HK22 – Cohesion coverstock with Carbon Fiber Infused (CFI) technology, creating explosive hook potential and unparalleled durability. The aggressive 500/1500 grit finish bites into the lane, while the eye-catching four-color swirl design makes sure your game turns heads before you even throw your first shot. This isn’t just the strongest Effect—it’s a new benchmark for power and performance. You asked for more teeth, more traction, more dominance.
