This special coffee cup comes with special items like coffee beans that help you cool your freshly brewed hot coffee to the right temperature so you can enjoy it as soon as possible. When the temperature of the coffee in the cup exceeds 60 degrees Celsius, the special fillers in these "coffee beans" melt, thereby absorbing heat to reduce the temperature of the coffee. Conversely, when the temperature of the coffee in the cup is too low, the filler will re-solidify and release heat to keep the coffee warm. After use, only need to take out clean, very convenient.
