Pour your hot beverage into this ceramic mug and watch your personalized image or message magically appear. These heat-sensitive 11oz mugs change colour when hot and return to black when cold.
These custom printed mugs dynamically react to heat and change color and message in the most amazing way. When the mug is cold, the mug turns black. When pouring a hot drink, the mug turns white and any images that are sublimated onto the mug will appear. Not Dishwasher or Microwave Safe.
