Kettles with beautiful design. Allegedly steel. Advantage is that fit only 1.5 liters of water. More needs not to be filtered coffee in a thermos. We had the Kettles 2 times each for 14 days in camping holidays in use and the lower seam is inside all around set a lot of rust, so that we no longer use it for reasons of hygiene. Therefore, only 1 star. Not recommendable.
