A magic mug is a cup that changes color. It can be heat sensitive, cold-sensitive, or employs both technologies on the same mug.
How does a magic mug work?
The color-changing effect is created by the temperature-sensitive material printed on the mug. The material is non-toxic and lead-free.
The heat-sensitive mug changes color when drinks (such as hot coffee and tea) over 80°F or 40°C are poured in. In comparison, the cold-sensitive cup changes color when the mug holds cold or iced drinks under 50°F or 10°C.
Because the mug's ceramic walls are quite thick, we recommend you to use hotter or colder drinks for better color-changing performance.
What is special about the Onebttl magic mug?
We utilize the coatings' color-changing properties to design interesting, funny, and original magic mugs covering various topics (cat, dog, llama, flamingo, owl, etc.) and different recipients (coworker, dad, dog mom, fishing lover, etc.). We hope our magic mug can make you happy and smile every time the cup changes color.
How to maintain your magic mug?
Please do not put the magic mug in the dishwasher or microwave oven to better protect the color-changing coating. Also, do not scratch the coatings.
