You think it’s just an average mug. That is until you pour in the boiling water to make a cup of tea! As the cup fills with hot liquid, the colourful spring will appear coiled around your mug. The mug is ceramic and uses heat sensitive ink which allows the image on the mug to change depending on the temperature of the liquid within.
The Questacon Spring Mug is made from quality ceramic. Do not wash in a dishwasher or soak for extended periods of time. Do not put in microwave.
