Frank Green Ceramic Reusable Bottle with push-button lid is made with a ceramic inner layer, making it stain and odour resistant, and a stainless steel outer to maintain the heat of your drink while keeping your hands cool. It looks beautiful, maintains the liquid temperature you desire for hours and tastes the way you intended (no nasty metallic flavour here) plus you can be confident knowing it won't spill in your bag when you're on the go. Capacity: 20 oz. Comes in black colour.
