This is sure to be a big help in the coming cold season! It's a Thermos soup jar. While 270ml is the mainstream size in this series, this one has a rare 300ml capacity, so it holds plenty. It has an inner lid, so you can store your food without leaks and keep it warm. The wide opening makes it easy to put in large ingredients like pot-au-feu and stew, and it's easy to eat from. In the summer, you can put in things like bite-sized ice cream with a cold pack and take it with you when you go out. *There is no guarantee it won't melt. It has built-in stainless steel and is excellent at keeping things hot and cold. Green is a very popular color. Because it's a discontinued item, it's a rare item that's hard to find in this capacity and color! It's new and unused, but it has been opened. I will sell it to someone who understands this. Immediate purchase is welcome. - Brand: THERMOS - Capacity: 300ml - Color: Green - Material: Built-in stainless steel - Lid color: Brown It comes with the box, instructions, and all accessories.
