Our development team worked diligently on creating a urethane ball that would meet the standards of Hammer fans. Purple Urethane Hammer changed the modern game by introducing a urethane to the market like no other ball before it, so we know how important urethane is to the Hammer fans. This new Black Pearl Urethane will be an excellent compliment for those who love the Purple Urethane and the NU Blue
