Product Description
Another exciting release for Hammer is an innovative polyester ball, a Black Widow Viz-A-Ball… with the Gas Mask core! This exciting ball provides the hitting power and flare the core offers and takes the Widow polyester line to the next level with full Black Widow images. Spare balls with a performance core have been popular for bowlers who want a harder-hitting spare ball or a ball for extremely dry lanes. Never before has a Viz-A-Ball featured a high-performance core, and there’s no better core or line to launch such a fantastic product.
