What a great new item! This mug is not only a great conversation piece, it's also very practical. No need to wonder if your coffee has cooled to your perfect temperature, now you can see exactly how much it's cooled. In durable porcelain, each mug features a battery meter graphic with a white outline. When your drink is over 36c the meter lights up. The hotter it is, the higher the meter reading. Get to know your perfect temperature, and you'll always know the right time to drink your coffee.
