The Northern Lights, or the Aurora Borealis, is an amazing astronomical phenomenon, envied by people all over the world. This mug takes that beautiful sight and sets it in the spotlight. As the mug gets warm, the northern lights image comes through, for all to see and admire. The heat-reactive surface reveals the northern lights 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. Dishwasher and microwave safe!

.: One size: 11oz (0.33 l)

.: Ceramic material with black exterior and white interior

.: Heat-reactive design

.: C-shaped handle

.: Glossy finish

While the mug itself is dishwaser safe, I recommend washing by hand as the hot water from the dishwasher will eventually fade the design.
