The BlenderBall is springy and bounces off both the top and the bottom of the bottle, working against the liquids. Add ingredients like peanut butter, applesauce or yogurt to your protein or meal-replacement shakes for added flavor - the BlenderBall whips them in with ease. The BlenderBall will never rust, chip or peel. Every BlenderBall is manufactured using a unique multistage process designed to ensure safety, quality, and longevity.
