Not only are these 10 oz. water bottles cute and fun, but they are also functional and practical too.  The Tritan™ material is tough, BPA free and shatter resistant.  The double wall construction helps to keep your child's favorite beverage at the right temperature longer which makes them an ideal choice for lunch boxes.  They come with a twist-on lid that features a clear flip-up spout and attached internal sipper straw.  The lid also sports a convenient handle, so they are easy to carry or attach to a back pack.
