Patented features like the glue channel on the outside surface of each insert aids in cleaner installation and preventing glue from seeping to the surface of the bowling ball. Helpful size indicators can be found on the outside and inside of each insert.

• Side 1: Power Nub - Lined with rows of small, raised bumps, the Power Nub has a very sharp feel and is not for the faint of grip! This style is recommended for a strong grip.
