Each water bottle in this Marvel Spidey and His Amazing Friends set holds 16 ounces, with an antimicrobial spout to help prevent the spread of bacteria. A cover keeps the spout clean when it's not being used, and it doesn’t leak when it’s fully closed. These bottles can be tossed into a bag for worry-free travel, or carried by hand using the built-in lid loops. Made of durable plastic, the drinking bottle set is BPA free and dishwasher safe, but should not be microwaved. They're sturdy enough to bring on everyday adventures and feature fun artwork to help make hydration fun for kids!
