Hammer Black Widow Savage Overseas Bowling Ball
For Black Widow, the engine that is the source of power, the “gas mask core,” is an immovable item and a condition of existence. When considering the evolution of the series around this gas mask core, the cover stock update is inevitably the target of development, but the hammer development team is not limited to changing the cover stock type, expanding the possibilities of the Black Widow series.
Overseas bowling balls are approved for all sanctioned USBC league and tournament play, but may not approved for PBA competition. Please check all rules and regulations before competition.
