Your CuppaCoffeeCup is top-drawer dishwasher safe, however, we recommend hand washing as it is less abrasive, meaning that the gorgeous design on your cup will stay looking amazing for longer.
Reusable cups from CuppaCoffeeCup are designed for espresso coffees. Therefore the maximum temperature intended for use in a CuppaCoffeeCup is 65 degrees celsius. They are not recommended for boiling liquids such as tea or long blacks simply because the heat comes through the cup and can burn your hands. You can still use for boiling hot drinks, it is safe to drink, just leave the cup on the kitchen bench until your drink has cooled.
CuppaCoffeeCups are freezer safe and microwave safe with the lid off.
