That's right! Nothing like it has ever hit the bowling lanes before. Scientifically formulated construction of 100% urethane with a unique designed weight block that passes through the center of the ball. The black buffed grenade strikes through short and medium heavy oil like no other ball can.

The black buffed Grenade is custom engineered to go long, and finish with enough lethal hooking action. Polishing the Grenade, this unique weight block design allows the ball to be used on a hooking condition.
