When you pour yourself a nice hot chocolate, coffee, pumpkin spiced beverage or tea in one of our Transforming Mugs, it changes everything – including the mug, itself. Watch the night before Christmas turn into Christmas morning with just hot water. Presents appear, stockings hang and someone has eaten the cookies! 12 oz. / 350 mL 12 oz.
