Stackable Bento Box Stainless Steel Lunch Boxes Insulated Detachtable Food Container with Handle Leakproof Lunch Containers for Adults(Black-2 Tiers)

I bought this thinking I could put hot lunches in it. It's not waterproof and is cheaply made.There are flimsy pieces of plastic that go on top of the stainless steel. A tight seal is not obtained.

Very good product
