The best mixer since the wire whisk. Congratulations. You own the best! Gourmet cooks have relied on the wire whisk for hundreds of years to blend their ingredients into a smooth and light consistency. Now you can do the same with the BlenderBottle. It's perfect for mixing everything from creamy smooth nutrition shakes to salad dressings, marinades, and fluffy omelets. It also makes a great water bottle. Simply drop the BlenderBall Wire Whisk into the BlenderBottle along with your ingredients, screw on the lid, press down the flip top, and shake. The patented BlenderBall moves freely throughout the bottle as you shake, mixing the thickest ingredients with ease - it's made of electropolished surgical-grade stainless steel and is designed to remain in the cup until you've enjoyed the contents. The BlenderBottle is no ordinary bottle. BlenderBall mixer inside. Easy-grip design. Ounce and milliliter markings. StayOpen flip top. Easy to clean. Dishwasher safe. Large drink/pour spout. Secure screw-on lid. Wide opening for ingredients. Fits in most car drink holders. No electricity or batteries required. Patented. Made in China.
