500ml green soup jar with thermal insulation and cooling function. - Brand: THERMOS - Capacity: 500ml - Color: Green (Yellow-green, a bright and beautiful color) - Material: Stainless steel inner - Function: Keeps warm and cold - Usage: Perfect for lunchtime I took it out of the box intending to use it, but I never did. The black part of the inner lid seems a bit cloudy, not shiny, though I'm not sure if it was like that from the beginning. Please be aware of this. Thank you for your consideration. The shipping method may be changed to Rakuraku Mercari Delivery. Thank you for looking.
