Unique product. Worth paying. Food remains absolutely hot and fresh, I tried for seven hours. Two suggestions what I felt - the grips of the containers need to be more deep because it's little difficult to bring out the extreme last bowl at the bottom, it slips. Second, I think instead of all the four containers vertically arranged, if something can be done like horizontal arrangement, two columns with two containers each, rectangular shaped, like the one available in glass model with normal bag. I think that will be easier to carry. This one looks very big and gives a little odd feeling in the office environment. The product is simply superb and I am extremely satisfied.
this is airtight container with lid and beautiful lunch bag …you can carry easily and take it office and your work place 👍🏻
