The Magic Color Changing Coffee Mugs is a ceramic coffee mug that will change color due to the temperature changes. It will change from dull-black to vivid image only when it's filled with hot liquid (no less than 70 centidegree). This mircle keeps happening as long as the temperature stays high. It is time to pamper yourself with your own self-designed mugs. It is a perfect gift for friends and families. It can be used in microwave, oven, dishwasher and freezer. This remarkable coffee cup transforms from black to your personalized photo when you add hot liquid.
