Hammer is excited to release 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.

GAS MASK CORE

The Black Widow Viz-A-Ball features the original Gas Mask core shape the bowling world knows and loves and is combined with a Carbon Fiber outer core for durability and power. This familiar core system is wrapped with Polyester and has a Crown Factory Polish finish.

Hammer recommends Tough Scrub to keep your Black Widow Viz-A-Ball Performing its best!
