Is it the metal soup/rice (outer) container that is insulated, or the entire lunch box container itself?

Not really "insulated" the lunch box is padded. Food doesn't stay hot it more or less stays warm. The small round container has a special lid that keeps foods warm as does the larger bowl. It's quite odd. The lid you see on the canister is the lid for the larger bowl. So the way it shows it in the little booklet that comes with is that the tight fitting packing of the two in the canister and the snug fit lids is what keeps the foods warm. My son still says he has to stand in line at the microwave anyway if he has time. Otherwise it's just warm like the last one to come to dinner just before everything gets put in the fridge.

The whole lunch box is not insulated, it is only the metal soup/rice container. But the instructions are only in Japanese so I do not know how to actually heat up the container.

Only the metal container, but since I never opened the box, I could not actually tell you. I did not need it in the end and I had to ship it back to Japan to return it so I still have it. For the person who wants to know how to heat up the container, put boiling water in it for 10 minutes and it will stay warm.

Just the metal container. The inner most container has like a venting type cover and the top container has a screw on lid that fits perfectly in the metal cylinder.

The removable food container is not designed to keep food cool. Food should remain refrigerated until you are ready to begin reheating it with the Lunch Warmer.

This product is NOT insulated container. It's a plastic plate with a tightly-sealable cover.

Ifbyou are talking about the container that holds the rice when it is cooking, then no. That is a some type of metal.

Yes, the lid is plastic, if the thermo is not up right the food can make contact.

The only material that could potentially be scratched off of this container might be the "Thermos" lettering that you see at the bottom of the container. Other than that, nothing can be scratched off. I have one of these containers for each of my kids. This one is for my middle school child and has worked wonderfully. They keep the beverages very cold. Ice is still present when we clean them out at the end of the day. The other big sell for me is that they don't leak. I won't use any other containers in lunches for fear of soggy sandwiches! Highly recommend.

It's decently insulated. It would keep food drinks cool for a couple hours without ice I'd think. We use cooler packs a lot which are nice because they don't melt

Yes. It is insulated,but if you live in a warm climate I would add the ice pack. Hubby says his cold water bottle keeps stuff pretty cold tho. Also I dont pack to much that has to be kept cold. Just sandwich, salad and such. He hasnt complained yet!

I have been using my insulated lunch box with a reuse able ice pack in it. It has worked great so far. The bags don't leak and don't take up a whole bunch of space. I pump at lunch so the food leaves and the bags go in.

There are 2 separate containers (the upper has a removable divider cup)which both go inside. One has a thermal non-watertight lid and is designed to keep food hot. Both need to go inside the outer jar to be stable, so side items will get heated to at least room temperature. If you want to keep the sides cold, you should get the other type that has a thermal jar and separate side containers. Zojirushi Mini Bento Stainless Lunch Jar Set

The lid is not insulated, only plastic, but my husband also works in very hot weather, when using the cold packs (plastic) this is an amazing cooler, as my husband works construction, and this is big enough for a couple meals and extra drinks for the job site, I would highly recommend it. We use it when we go to the zoo etc. with the kids too! Works Great!

Well this has not insulation, it's a thin layer of stainless steel. If you put this in a cooler the food will stay cold. I use it for salads and no hot food.

No. I use a regular thermos lunch box and put soup in this jar with a large spork, sandwich, soda, and a couple of candy bars.

Yes, it is insulated with a thin, white plastic liner. Btw, the tin rusts really easily so make sure you keep the metal parts wiped down and dry.

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

Yes the carrier is insulated. This was a gift to my daughter-in-law and she is loving it.
