Add a pleasant twist to your morning routine with this glossy Throwsticks "Magic" Mug. It appears black when cold, but reveals A Wirlki rotating around the outside, on its path, when exposed to hot liquids. This mug a wonderful gift for your family or friends.

The surface is temperature sensitive and reveals a rustic greyish off white when put under a stream of hot water. It will darken wherever the heat dissipates, such as above the water line or on the handle, as it cools. Warm water produces hues of dark brown but when cold the cup is near black with the throwstick pattern barely visible from the surroundings. Rustic, beautiful and fun!
