Thank you for viewing. This is a brand new, unused Storm Ion Pro bowling ball. Weight is 15lb 4oz. Top weight: 3.14 oz, Pin to CG: 3.5 inches. Mass Bias is straight. Please check the images for details. It has been stored in a bowling alley locker since purchase. It was unopened until the photos were taken, but has been stored in a bag. I am selling it to organize my locker. A ball polisher is also included as a bonus. This is a discontinued item, so it's rare to find a new one. If you have any questions, please ask. Shipping will be via Yamato Transport.
