The colour-changing mug is good for a surprise every morning. Because as soon as a hot drink is poured into the cup, your chosen motif becomes visible. At normal temperature, the motif is only recognisable if you look very closely. This magic thermal effect makes your coffee or tea taste twice as good. The high-quality colour-changing mug is made of ceramic and has a tight-fitting handle for a comfortable grip. If you're looking for a fun gift idea, this colour-changing mug is sure to be a great surprise.
