WoW! Double-walled, vacuum-insulated food container with carrying ring made from recycled stainless steel and plastic screw-on lid. 100% leak proof. The food container has a large opening for easy filling and cleaning. Keeps food and drinks warm for up to approx. 4 hours and chilled for approx. 20 hours. Perfect for bringing, for example, a (hot) lunch, soup or yoghurt with fruit. Not dishwasher-safe. RCS-certified. Total recycled material: 73%. Capacity 500 ml. Stainless steel can be recycled many times whilst retaining the quality of the material. By using recycled stainless steel, fewer new raw materials are needed. This means less energy consumption and less use of water.
