Emblazoned with officially-licensed Marvel logos, authentic BlenderBottle shaker cups get a superhero makeover! Marvel's Black Widow is represented with logos on 24-Ounce BlenderBottle Strada Stainless Steel Shaker Bottles. The BlenderBottle Strada Stainless Steel Shaker Bottle with Locking Lid features an easy-open/easy-close push-button flip cap with a sliding lock to prevent accidental opening. At 24-ounces (interior measurement markings to 20 ounces), the insulated bottle has plenty of room to mix protein powders, supplements, or meal replacement smoothies, using the BlenderBall Whisk, which delivers smooth shakes in seconds without batteries, cords, or hassle. It can also be used as an insulated water bottle. Screw-on lid is leakproof, and the wide mouth accommodates oversized scoops and makes for easy cleanup; a rounded base ensures thorough mixing. Double-wall vacuum insulation keeps drinks cold for up to 24 hours. A flexible, ergonomic carry loop provides a comfortable hold, and a place to attach keys or hook the bottle to a gym bag. The BlenderBottle Strada is made from high-quality, BPA and phthalate-free materials. Lid is dishwasher safe; hand wash cup. Not for use with hot liquids. Manufacturer’s limited lifetime warranty.
