Thank you for viewing. This is the Hammer Redemption Pearl. The ball surface has a 1500-grit polish, allowing it to glide smoothly through the front part of the lane while providing a solid roll and sharp backend reaction from the mid-lane onward. Pearl balls, compared to solid balls, tend to react more sharply in the mid-lane to the back end. This model is recommended for those seeking length and a strong backend. This series also includes the "Redemption Solid," a solid cover version. By using them separately depending on the oil volume and lane conditions, you can achieve a more stable line. 【Specifications】 ・Manufacturer: Hammer ・Model: Redemption Pearl ・Coverstock: Aggression NE Pearl Reactive ・Core: Redemption Asymmetric ・Finish: 1500-grit polish ・Weight: 15 lbs ・Condition: Scuffs and minor scratches from use (does not affect performance) Please only purchase if you understand that this is a used item.
