The soup container, lid, and water container are made of stainless steel. The lid features an opening for a spoon. The body is made of impact-resistant material. The heater is equipped with a thermostat for temperature adjustment, and a spoon is included in the set. It is recommended to use water with a hardness of up to 6°dH (according to the German scale).
