About this ball
We have taken the top-selling Hammer balls of the last three years and combined them into one exciting ball. We’ve paired it with the incredible looking Black Widow Urethane Pink Pearl. The Pink Pearl was extremely popular as a reactive Black Widow, and we expect it to kill since it now uses the Purple Pearl Urethane cover formulation. The Black Widow core makes it an excellent choice for bowlers who didn’t see enough hook from the Purple Pearl Urethane. And just like the Purple, every competitive bowler will have to have this ball in their arsenal.
