A 12 oz. kid size double wall, copper vacuum insulated bottle that keeps drinks cold for 9+hours and hot for 3+ hours.  It is crafted with high quality, food grade 18/8 stainless steel (304 stainless steel) which is resistant against bacteria, mold, and lingering odors due to its non-porous nature. The 18% chromium and 8% nickel material composition makes it less likely to rust or corrode too. It features a twist on lid with a flip spout and looped handle that is ideal for small hands. Made beautifully to last!
