The heat-reactive surface reveals the design once the mug gets warm. The ceramic cup will go back to its original black outside and white inside when it cools down. The C-shaped handle helps keep a sturdy grip. It comes in one size – 11oz (0.33l) – plenty for that big morning cup of coffee.

While the mug is dishwasher safe, I recommend washing by hand as the hot water from the dishwasher will eventually fade the design
