This Dr. Seuss ‘Resting Grinch Face’ Heat Reactive Mug initially shows only the large black mug with two bright yellow eyes only. Add hot water, and the Grinch appears on the mug. The back of the mug states in white ‘Resting Grinch Face’. The mug is made of high quality ceramic and holds 18 oz. of your favourite Cupper’s coffee. Because of the nature of the heat-reactive image, this mug should stay out of the dishwasher and microwave.
