E-R1™ Solid Coverstock

Wrapped in our cutting-edge EXTREME-Response Solid Reactive cover better known as E-R1™ Solid Reactive, the Perfect GEM creates a distinct advantage over its predecessors. While the original GEM was known for its early, "snow-tire" traction, the NEW E-R1™ solid material provides more of an “off-road” type of traction that allows the ball to clear the heads more easily while providing EXTREME response down lane and through the pins.

The Result: You won’t see it burn up too early. Instead, you get a ball that saves its energy for a continuous, booming shape down-lane.

Why the Perfect Gem Belongs in Your Bag

• Versatility: More "usable" on a wider variety of heavy to medium-heavy oil patterns compared to the original GEM.
• Enhanced Shape: Expect more "pop" off the end of the pattern without sacrificing the stability of a solid coverstock.
• A.I. Powered: Our latest core tech ensures better energy transfer to the pins, even on off-center hits.

Ball Maintenance

Over time, friction and lane shine can alter your ball's original 2,000-grit factory finish, affecting the traction and motion it was designed to create. To restore the Perfect Gem back to its intended factory finish, follow Storm's recommended resurfacing process for a 2,000-grit surface. After each session, clean your ball with one of Storm's cleaners to remove oil and debris. Routine maintenance helps preserve surface integrity, extend performance life, and keep your reaction closer to out-of-box.
