JoPo Inner Thumb Slug Drilled

This is a great addition to any bowling ball, especially having the ability to keep the thumb hole consistent ball to ball. This is the 3rd ball from Buddies with a Jopo slug. Will not be going back to traditional! Easy to install/swap.

I am Pro Buddies anyway and the fact that Fell in love with JoPo thumbs and Buddies made a mold of my thumb and it comes out perfect unreal fit and gives so much control of your bowling ball, love it,,,

First time going to a interchangable thumb - Extremely happy with the product and performance. Solid construction and love the screw in feature.

Good product consistent thumb fit
