Bowlers prefer our Urethane Solid over any other brand because of the consistent feel, smooth release and clean finish it has to offer. Pro shops prefer them because they are the easiest to cut, carve and finish. Our Duo-Color Urethane Solids go a step further to help pro shops consolidate inventory while at the same time expand color selection. It just doesn't get any better!

What are they used for
This is used to go in the thumb hole so your not directly feeling core material or coverstock material. They will drill a hole out in the thumb and put the slug in there and you would use that like you would use an insert. If you drill a hole in the ball, you can feel the core material and with a thumb slug it will make it a smoother feel.
