How is the bento set heated?

By boiling water and placing it inside large metal container. Than you place two containers with hot food inside water and it seals it. Water never gets in foof and it keeps it warm for a long time. Very happy with it

It's not heated. The individual containers are microwaveable, but you have to heat the food for the thermal portions and then store it in the thermal container. It will stay warm/hot for a long time - the design is good - but it doesn't heat itself.

They do get hot. I would suggest a kitchen towel or a pot holder when first getting them out. Also, the big plates are too big for your average microwave. So that might factor into your purchase as well. They are nice though. I have used them for over a year and I don't even have a chipped one yet. (With 2 kids that also use them regularly, that is an amazing feat.)

The bento box is microwaveable. The lids fit securely, but I would not put something like soup in this container.

It is made of plastic. As for heat, I ruined one because I put it in the dishwasher. But, I put the new one in and it is fine. So, boiling hot may not be the best.

You're not really supposed to put warm food in a bento box. Warm food causes water to condense on the inner lids, which if left unrefrigerated for too long can allow for bacterial growth (also your food can get soggy). Plus, the inner sealing lid is not microwaveable. Exposing it to the high temperatures of steam could warp it, damaging its waterproof ability.The container itself IS microwavable, just not the waterproof lid. My suggestion is to put food in at room temperature, then warm it up in a microwave if one is available to you. You could also look into bento recipes, which are often designed to be good both warm and room temperature, if you don't have access to a microwave.

Th handles get hot, not red hot. We use pot holders when moving the pan. It is an excellent pan.

The metal does not retain the heat of the food. It's not insulated. My standard lunch would be a salad, PB&J; sandwich, and some fruit and nuts. I have taken leftovers but needed to warm them up in the microwave after I transferred the contents (pasta) to a microwave safe bowl. Do not attempt to use the stainless lunch box in the microwave. On the plus side, the lunchbox still looks great and I still get compliments on it.

Low to medium heat, and patience (and some passion too ;) ).Also, I grease them with coconut fat after usage.

It is hot but you can adjust the temperature to a lower setting. I use this for buffet servings.

I have put boiling water in them and a mixture of hot butter and chocolate. I am not sure if that is piping hot food or not but I have never had any problem with putting anything hot in them.

I have placed them in boiling water before to heat contents. Just don't let the bag rest against the hot pan out of the water and onlyBoil long enough to to heat the contents

The top tier with the vents is for foods that would go soggy/gross in a closed container. Fresh things like cherry tomatoes, mandarin oranges, grapes, crackers, cookies etc and foods put in warm like rice, sandwiches, rolls, etc. If youre worried about things getting in your food, put your bento in a special bento bag. You can also line the box with cling film or wax paper before you put food in!

Not much on the back and sides. The front is glass so there should be heat. If you want to change the cooking time, or temperature, it is minute by minute or degree by degree- with a dial. Some idiot was on the design team.

They can get hot. For example I microwaved broccoli in one of the bowls with a plate set over the top yesterday for 3 minutes and I had to usepot holders to take out out. Just a typical plate of food for a minute or two doesn't get overly hot.

I haven't used it for heat as of yet, but from the instructions, you heat the packs in the microwave.

It is thin metal with fire inside. It gets VERY hot! That said, I've roasted marshmallows with my three year old twins. You just have to watch them and teach them to stay back.

No, they are not hot. I put them in the microwave often and never have a problem.
