Performance you can feel from the first shot. Our development team worked diligently to create a urethane ball that meets the standards of Hammer fans. The Black Pearl Urethane is an excellent complement for players who love the Purple Urethane and the NU Blue.

Built on the LED core with the Urethane Pearl 78D cover, it delivers the smooth, controllable shape urethane players trust with a touch of pearl length on medium-to-dry lanes.

Who It's For

• Urethane players — controllable urethane shape with a cleaner pearl look.
• Medium-dry conditions — reads smooth and predictable when the lanes open up.
• Purple Urethane / NU Blue fans — the natural complement to round out the bag.
