I"In the same way, let your light shine before other, that they may see your good deeds and glorify your Father in heaven." ~ Matthew 5:16

This mug start black, but the heat-reactive surface reveals the lightbulb design inspired by Matthew 5:16 once the mug gets warm. The ceramic cup will go back to its original black outside and white inside when it cools down. It comes in one size – 11oz (0.33l) – plenty for that big morning cup of coffee.
