Insulated thermal food container for on-the-go. The Sigg Thermo Container Gemstone Food Jar features a subtle design from the Gemstone series, making it ideal for lunch breaks at work, school, or outdoor meals. Thanks to the insulation of the Gemstone series with a narrow, double-walled vacuum insulation and copper coating, this thermal food container is suitable for both cold and hot beverages, keeping them warm or cold for up to 11 hours. Additionally, meals can be eaten directly from the insulated container using the integrated cutlery, with the lid of the food jar serving as a bowl. Made from high-quality 18/8 stainless steel, the food container is robust, although hand washing is recommended for a longer lifespan. The container is made from food-safe materials and contains no harmful substances.
