Equally at home in your kitchen or in your office, the LivWELL BlenderBottle Shaker comes with a patented BlenderBall wire whisk, pour-through lid, and flip-snap cap (already fully assembled). Whether you're mixing a protein shake, salad dressing, smoothie, or pancake batter, all you have to do is add the ingredients, drop in the BlenderBall, close it up, and shake. Ounce and metric markers are even printed on the side of the bottle, so you can double-check your measurements before shaking.
