I have many plugs. The number of Gs thrown is also unknown. I have plugs for right-handed and left-handed bowlers. How about trying them out or using them for practice with a Covert Revolt? I offer free surface processing for plugged balls and balls that have been plugged for you. Abralon sanding #360 #500 #1000 #2000 #4000 Polished finish, etc. Plugging is 2500 yen, and plugging & drilling (solid grip included) is available for 6000 yen. Please contact me in the comments. If processing is required, it may take some time. Please understand this in advance. Also, if an issue occurs during processing that makes the ball unusable (such as the ball cracking), the transaction may be cancelled. Please state your desired price when negotiating a price reduction. I may also be listing on other sites. Please understand that it may be sold out.
