Represent your favorite superhero - bring out your inner flash during your pre, present, and post work out! Our shakers offer top quality performance and shows off a bit of who you are as well. Every athlete is unique and special in their own way. Let's be honest, no matter the level of fitness, this flash bottle is perfect for any super hero fanatic. Leak-free guaranteed - no other shaker cup on the market is designed to endure the wear and tear that a peforma perfectshaker does. Our proprietary design has been optimized to ensure that no matter how the cup is used, it will not leak. Actionrod technology - this patented shaker agitation element is scientifically developed using the laws of motion. During the blending process the agitator and rod combine to form a high performance piston, colliding with high momentum in the opposite direction of the mixture. This rapid collision builds momentum within the cup as the fluid mixture accelerates and impact becomes intensified. The explosive impact results in instant emulsification and perfectly blended drinks every time. Duraplex shatter resistant plastic - not all shaker bottles are made the same. The quality of the plastic used and its overall density play a key role in how shatter resistant it is. Performa perfectshaker bottles use a specialized blend of polymers that ensure maximum shock absorption and elasticity. Bpa free, dishwasher safe with extralast ink - our shaker cups are 100% bpa free for the safest supplement consumption. Our extralast ink ensures that the design on your shaker cup stays pristine wash after wash.
