Fun "Coffee before my mouth gets involved" black to white color morphing mug! The heat-reactive surface reveals the funny saying once the mug gets warm and then 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 – plenty for that big morning cup of coffee.
