The special thing about this cup is its heat-sensitive layer. When not filled and cold, the cup is completely black and the lettering OFF is visible. After you have filled it with a hot drink, the cup turns white and the lettering ON appears. So the cup works just like my colleagues in the office. Those who are afraid of chemicals can be reassured, the cup is completely made of ceramic. Furthermore, there is no layer added inside the cup, so it remains completely white.
A warning is to be given to all dishwasher owners. Unfortunately the cup is not dishwasher safe.
Lovers of tea and coffee will surely be pleased about this cup. If you like it a little more fantastic, take a look at the magic unicorn cup.To the gadget
