The listed price is for the ball itself, but drilling services are available for an additional fee. The fee will vary depending on the specific work required, but will be offered at a price below that of a bowling center. We can also handle difficult IT-related work; please consult with us beforehand. We will determine the layout by consulting with a dedicated driller while you send us a measure sheet, etc., so please feel free to ask any questions you may have. This is a new Storm Infinite Physics ball from High Sports. Please refer to the outer box in the photos for the specifications. The following is quoted from High Sports: The long-awaited world release version of the Physics, the "Infinite Physics," is here. By adjusting the amount of pearl material, it goes straight to the breakpoint without slipping on the front of the lane. The Atomic Core's unique, narrow width of maintaining power in the vertical direction allows it to smoothly enter the pocket, highlighting the Physics series' appeal of good pin action. By finishing the surface with 4000 grit, it is not easily affected by the density of the oil, resulting in a product with excellent control performance. Most balls with sanded surfaces show some power loss when hitting the pins due to friction from the front of the lane, but this series is an exception. The ReX Pearl material this time has a lower pearl content than PURE, and the back-end hook is slightly smaller, but it is easy to control and enter the pocket even if there is a large difference between the dense and thin parts of the oil.
