These mugs are super popular gifts for friends and loved ones. This one changes color and will be the gift that keeps on giving. 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 – plenty for that big morning cup of coffee. Handwash recommended.
