Drink the moon is an innovative coaster design, its color will be changed at different temperatures.
In general, this coaster is black. The coaster will gradually become the moon’s appearance if it is the hot tea or coffee in the cup. If the cup is filled with cold drinks, the coaster will turn to black. Depending on the size of the cup and the location of the cup, the coaster will show us four different shapes: the crescent moon, the full moon, the first quarter moon and the last quarter moon.
