More than a spare ball. The Black Widow Spare+ pairs the iconic Gas Mask core with a polyester cover to create a spare ball that punches above its weight. It delivers the pinpoint accuracy you demand for spare shooting while offering enough core dynamics to double as a weapon on extremely dry lanes and short patterns with low volume.

Whether you're converting corner pins or trying to survive a burned-up house shot, the Spare+ is ready. Wrapped in a striking white pearl finish with real sparkle — every bit as bold as the Black Widow name deserves.

Who It's For

• Spare shooters — dead-straight polyester reaction with the core dynamics to keep it steady on corners.
• Dry-lane players — a real option on extremely dry lanes and short, low-volume patterns where reactives are too much.
• Two-ball bag bowlers — the perfect straight-shooter to pair with your strike ball.
