Hi, I read from another reviewer that you can heat these in the microwave. Does the instructions state that? Thanks in advance. : )

No it does not, and I would not recommend it as there is a small metal-type disc inside. Unless you want to cause a fire and possibly obliterate your house, but that's not an efficient way to keep your hands warm. Just boil it on the stove per the instructions.

You can, but this brand does not state you can microwave, if you do not microwave carefully they will EXPLODE!!!

They heat up by bending the "coin" in the pack. Once the now solid pack is no longer warm, you boil it for 6 minutes and it turns liquid again. I don't know about putting it in the microwave to turn it back to liquid and make it ready to activate again but because the "coin" is a thin metal, I imagine you really wouldn't want to.

Yes, I've used them in the microwave multiple times. However, I would recommend keeping an eye on them just in case, and don't put them in for a really long time. A minute to two minutes or so is fine.

I'm sorry, I haven't used them in the microwave. I tend to use glass in the microwave.They are holding up very nice though in the dishwasher.

I hadn't considered microwaving them. I would think that since there is some foil in their content, I would say it's not a good idea to microwave them. The bags are terrific, though. I use them every year for an annual cookout that I host. After putting the hotdogs in the buns and then in the bags, I put them into a huge covered steamer pan to keep the dogs warm and the buns soft. They are always a big hit.

these specifically say not for microwave on the bottoms. so while you could feasibly put hot stuff in them, if you microwave them, who knows what they are leaching out into your food. And I suspect they could crack or explode over time if you do microwave. anything that has "do not microwave" on it, I respect that.

Margaret, did not know you could microwave them. I have always washed them by hand. Nice to know.

I haven't tried to microwave anything in them yet. But they are gorgeous and nice sizes! Sorry I couldn't be more help!

I have not used them in the microwave yet, but I love them for the lunches. We have 4 sets and I plan on buying someone soon, because there are 4 of us that use them all the time.

never tried that - I've put them in a microwave to heat the contents...but that doesn't get as hot as 212

I've never tried that, but I'm leery at the prospect. I think they are meant to be used in the microwave, and could melt on a grill, but that's just my thoughts.

They are fine in the microwave. I have put them in the oven on 180 to keep the food warm and had no issues.

Yes. To add on to someone's question about how hot they get after microwave use, they are not even close to my old Pfaltzgraf set, which I couldn't touch with my bare hands. These get fairly hot after minutes of microwaving, but if you're just warming something up briefly, you can touch them and they won't burn you. They're awesome.

They do not get hot in the microwave at all. They can go into a regular oven or microwave oven.

They work beautifully in the oven...I coat with cooking spray before filling. I assume they would also be fabulous in the microwave, but have not used them that way.

I wouldn't put them in the microwave. I don't know why you would want to preheat these? They work perfectly and stay plenty hot while you're drinking your 2oz of delicious espresso.

I use them in the microwave. They don't get any hotter than any other dishware. Always use caution pulling anything out of the microwave.
