Supreme x Thermos Collaboration Stainless Steel Food Jar ○ Size: 14cm tall, 9cm diameter, 470ml ○ Heat Retention: Warm for 9 hours, Cold for 14 hours - This is a stainless steel food jar made in collaboration with Thermos. - It has a built-in folding spoon. - The double-walled stainless steel construction provides excellent insulation, so the outside doesn't get hot when you put hot food inside, and it doesn't sweat when you put cold food inside. I washed it once, thinking I might use it, but I haven't actually used it.
