Mod is made from a clear resin with several different pigments and powders added to make it look like a marble swirl bowling ball. Each ball will look slightly different then the next. Mod comes with new launch button assembly attached to it. This includes the ball mod, launch frame, lock down nut and switch. **Note this mod does not light up. Even though it is made from clear resin, with the additions of all the powders and pigments the ball is to opaque to let light through it**
