Emblazoned with officially-licensed Marvel Comics logos, authentic BlenderBottle shaker cups get a superhero makeover! Marvel favorites Captain America, Captain Marvel, Hulk, Spider-Man, Thor, and Iron Man are represented with their updated symbols on 28-ounce BlenderBottle Tritan Pro28 mixing cups. Shaker bottles include the BlenderBall wire whisk that moves inside the bottle as it shakes, mixing even the thickest ingredients with ease. BlenderBottles feature a secure screw-on lid, carry loop, wide mouth for easy mixing, and embossed markings that measure both ounces and milliliters. Pro28 bottles are designed with a rounded bottom for improved mixing. Dishwasher safe and BPA- and phthalate-free. BlenderBottle can be used as a mixer, a leak-proof water bottle, or without the lid as a super drinking cup. BlenderBottles are perfect for protein shakes, smoothies, pancake batter, scrambled eggs, drinks, dressings and meal replacements. Exterior measurements only go to 22 ounces on Pro28 (but actual capacity is greater).
