Holds approximately 500 ml. Our food jars are made from stainless, recyclable steel, same material as is used in the steel pans you have in your kitchen. Stainless steel is known as a safe choice as it has no type of coating inside the food jar. The caps are made from plastic. No traces of Phthalates or BPA have been found in the caps or cups. The vacuum flask has a double wall and base, and our test results show that hot liquid, which was 98 °C C when poured in, was just over 60 °C C after 7 hours.
The cap and drinking cup can be cleaned in the dishwasher. To take good care of the pattern on the outside the vacuum flask should not be put in the dishwasher.
