I'm Not Old. My Wrapper Is Just Wrinkled Color Changing Mug

Designed with a unique heat-sensitive coating, this mug not only holds your favorite drink but also delivers a funny graphic every time it changes color. It's the perfect funny gift for anyone who loves a good laugh, or maybe for that soon-to-be retiree who likes to chuckle! 

The heat-reactive surface reveals the design once the mug gets warm and then goes back to its original black outside and white inside when it cools down.
