Built specifically with Baby Formula and Protein Shakes in Mind this Mixing Pitcher is easy to use, fast, and efficient. Mixing Baby formula and Protein Shakes is made with just a few strokes of the mixing plunger. This quickly results in a clump free mixture that is easy to pour into another container. Tested with many brands of Baby bottles the pour spout is acurate and appropriately sized to easily fill your baby bottles. This also works well with most to go bottles for sports drinks and protein shakes. Easy to Clean - Unlike the others, our pitcher with mixer plunger has a straight minimalist shape that makes reaching all the corners of the container effortless. It is easier to clean than a regular juice jug - making it an excellent option for camping or outdoor activities. Great for mixing frozen juice concentrate, shakes, chocolate milk, powdered lemonade, fruit punches, iced tea, mixed drinks, protein shakes, baby formula and more! We have even used it to make pancake batter.
