It includes two cups (titanium and stainless steel) which together create an insulating cup and an aluminium pot with a capacity of 750 ml. The pot is anodized, not coated, which makes the surface of the pot extremely durable and prevents the food from sticking. A separate insulating sleeve for the large pot keeps meals warm longer.
