Think plastic can’t pack a punch? Think again. The Hammer Black Widow Viz-a-Ball is a spare ball with serious bite.

For the first time ever, Hammer has wrapped its legendary Gas Mask Core in a polyester shell — giving bowlers a spare ball with real performance power. Whether you're cleaning up spares or attacking bone-dry lanes, this Viz-a-Ball delivers more than just looks.

The iconic Gas Mask core — the same core used in the Black Widow series — sits at the heart of this ball, bringing high flare potential and hard-hitting dynamics to what’s traditionally a low-performance category. Paired with a polished plastic cover and reinforced with a Carbon Fiber outer core, the Viz-a-Ball is both tough and responsive.

Finished with a high-gloss Crown Factory Polish and decorated with full Black Widow imagery, this ball turns heads and turns frames into wins. If you're tired of your spare ball rolling flat or need something reliable for ultra-dry lanes, the Viz-a-Ball redefines what polyester can do.
