DARK BRANDON BE VANISHED.
This one changes color and will be the gift that keeps on giving. 
The heat-reactive surface reveals your custom designs 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.
