Gourmet cooks rely on the wire whisk to blend their ingredients into a smooth and light consistency. Now you can do the same with the BlenderBottle®. The patented BlenderBall® wire whisk moves freely throughout the bottle as you shake it, mixing the thickest ingredients with ease. Now you can mix it smooth—anytime, anywhere! 28-oz. capacity (to cup brim). Great for 8-20 oz. drinks, dressings, and other culinary uses.
