Pour hot liquid into this Wonder Woman Diana Prince Heat-Sensitive Morphing Mug and Diana, Princess of Themyscira appears. Behind her, vintage stars and her classic W-shield logo complete this nostalgic-styled design. The exterior of this 11 oz. mug transforms from black as hot liquid is added, revealing the hidden image in full vivid colors. Makes a great gift for fans of Wonder Woman and DC Comics. Hand wash only. Not dishwasher safe. Do not microwave.
