Our 316 surgical-grade stainless steel mixing ball is designed to help mix your shake ingredients to a smooth and light consistency every time. Simply add your child's recommended serving size to your Complete Kids shaker bottle with water or milk or a combination of both, drop the ball inside and shake for 10-20 seconds and serve.
