Thank you for visiting. This is a large-capacity 1500ml insulated lunch box. The inside is made of stainless steel, and it also comes with a container for soup. Chopsticks, a spoon, and an insulated case are included. As you can see in the 7th photo, it can be warmed by pouring hot water into it. Please check the 8th photo for the size. After purchasing it new, I used it once and then stored it at home because I didn't use it. Please understand that this item has been stored at home.
