The Black Widow series has been the most successful series in Hammer’s history at Ebonite International, and it is still the best selling franchise in the bowling industry. We’re continuing that success this season with Black Widow Sting. Black Widow Sting doesn’t just expand our performance range – it takes a gigantic leap forward in bowling ball motion. Sting pairs up our proven High Mass Bias Gas Mask Core with a new Violent Flip Reactive coverstock. Bowlers will look to the Sting on heavier to medium-heavy oil, as the Violent Flip Reactive cover is extremely aggressive, and comes sanded at 2000 Grit Abralon. The Sting gives bowlers that signature Black Widow series backend with even more power and aggressiveness.
