Bình Giữ Nhiệt Thực Phẩm Vegetable Garden Chilly's 500ml

Brought this on a hike and my pasta salad was still cold at the summit six hours later. The lid screws on tight enough that nothing leaked in my bag, which is more than I can say for my old container.

Filled it with hot tomato soup at 7am and it was still steaming at lunch. The airtight lid hasn't leaked once in my bag, even tipped sideways on the train. Six hours of heat is exactly what I needed for work lunches.
