Charming. Enchanting. Mesmerizing. Call it what you will, but Roto Grip prefers to call this wonderous and mystical jewel the Magic GEM. After months and months of mixing spell after spell in the R&D Lab, they managed to conjure up one the most prolific hybrid high performance balls that they have ever offered thanks to the powers of both the MicroTrax Solid and MicroTrax Pearl components brewed together to form the MicroTrax Hybrid Coverstock. So, if you are looking to put a hex on your adversaries, might we interest you with this powerful magical bowling stone. Trust them when they say, this isn’t just a bunch of hocus pocus.
