This ball was very easy to handle and served as a benchmark ball for me, but I'm selling it because I have too many balls now. Purchased new from a pro shop. Purchase price: 24,000 yen. * No outer box. * One all-plug. * Approximately 20 games bowled. * Finger grip outer diameter: 7/8 inch. * Span: Approximately 9.3 cm. * Thumbhole diameter: Approximately 2.3 cm. * There are some minor scratches, but the condition is good. * The plug color is partially missing, and the finger grip on the ring finger is visible, but I don't think it's very noticeable. * The grips will be removed and shipped for hygiene reasons. Please understand that this will be a simple package and read the profile before purchasing. ✜Product Description✜ The Solution series, planned in Korea and a huge hit in the KPBA, makes its debut in Japan. The "Solution Black" features the "RAD-A" core, developed to emphasize the backend snap, and the "NRG-2™ Solid Reactive" coverstock! The reason for its success is the smooth roll on the front part of the lane, combined with high stability, giving the impression of no slippage. The high inertia of the "RAD-A™ Core" weight core accelerates axis migration, resulting in a large flare width and a sharp, hooking motion. The intense pin action resulting from the remarkably sharp hook is a must-see. Also, despite its sharp movement on the backend, it is easy to throw and has good control, which is the biggest feature of this ball.
