I use these items when I worked in an office setting. I no longer work in an office and instead work out of my car so I do not use these any longer. The Bento box has two large areas for food and it included utensils. It is dishwasher safe at least I put it in my dishwasher, it has a vent on the top. If you want to heat up the top section. The thermos comes with its spoon and it holds a decent amount of soup I would say about a cup and a half half. It does keep it warm, it lays on its side in the lunchpail and I never had a problem with leaking. However, I always took it out of the lunchpail and sat it back up because I didn’t put hot soup in the fridge so it wasn’t on its side very long.
