The Storm Phaze II Bowling Ball is a high-performance ten-pin bowling ball designed for right-hand players weighing 13lbs. With a striking red, blue, and purple color scheme, this ball features a symmetrical core and is drilled to ensure optimal performance on the bowling lane. Backed by a one-year manufacturer warranty, this ball is perfect for serious bowlers looking to enhance their game with a dependable and durable bowling ball. Perfect for use in the United States Bowling Congress (USBC) sanctioned leagues and tournaments. I had this ball drilled but it has never been down lane.
