- From the manufacturer
The time of reckoning has arrived and the Roto Grip Kingdom welcomes the addition of the newest legend of the land. Bred from the original and designed to compliment its predecessor, the Cell™ Pearl will reign supreme.
The technologically advanced and performance proven Nucleus™ core delivers continuous predictable motion for all types of bowlers. The Cytoplasmic X™ pearl reactive coverstock is a first in the industry with the optimum amount of porosity and enhanced surface friction.
The synergy of core and coverstock on the Cell Pearl™ generates a strong angular move off the spot on those medium to lighter volume patterns with unprecedented predictability. This ball is the ultimate compliment to the original and will surely dominate the entire bowling kingdom.
