Thermal bowl with screw-on lid. Thanks to the thermo-insulating foam layer between the walls, the thermomass keeps your food at a constant temperature for a long time. You can use it at home, at work and on the road, in summer and winter. Great insulating properties. It is lightweight, easy to carry, the smooth surface is easy to wash. Excellent use on hot summer days for ice cream. The duration of temperature retention in the container depends on the ambient temperature, or the temperature difference between the outside temperature and the temperature inside the container. Place the container in the refrigerator for about an hour before putting cold food, e.g. ice cream, to prolong the cooling effect. When putting hot food inside, pour hot water inside the container and pour it out after about 1-2 minutes. The heated interior of the thermos will prolong the temperature retention effect of the food.
