The Black Widow, Hammer’s most successful line, is back at it, this time with a polished pearl that will get a ton of attention. Pink was incredible for the Widow series and the Ghost; a gorgeous white pearl version will be the next big thing.
GAS MASK CORE
The Black Widow Ghost Pearl 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 Aggression Pearl and has a 500, 1000, 1500 Siaair / Crown Factory Compound finish.
Hammer recommends Tough Scrub to keep your Black Widow Ghost Pearl Performing its best!
