Our 350 ml water bottles hold 12 oz of liquid - about the size of a store bought water, and the 500 ml holds nearly 17 oz. Each features your favorite super hero with a choice of Batman, Iron Man, Spiderman, Superman, and Captain America.
Each bottle is made of solid stainless steel, comes with a stainless steel cap with a flip-up/down sippy top and internal straw to reach the very last drop. Each bottle features a leak-proof twist-on lid, and double insulated floor to help maintain temperatures. The entire bottle is sustainable, eco-friendly, non-toxic, bpa-free, and can be re-used hundreds of times.
