A Circular&Co coffee cup is open when the push button is in the lower position and closed when the button is in the upper position.
To avoid dripping, do not fill the coffee cup over the maximum recommended line (on the inside of the cup).
Circular&Co coffee cups have a leak resistance guarantee only if the seals and pushing mechanism are clean. It is recommended to maintain the cup regularly after each use. It can be washed in a dishwasher, preferably on the top grate. If necessary, the push button can be removed for cleaning. See the instruction video below.
