Are these microwave safe?

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 looked up the bento on one of my fav bento sites jbox.com... "Microwave safe with the inner lids and covers removed."

Micowaving plastic is never safe, it leaches chemicals into the food and those chemicals are shown to be cancer-causing and hormone disrupting. Cancer centers tell people this, that's how I heard of it. Bento boxes are traditional asian lunch boxes meant to be filled with fruit, nuts and rice, foods eaten cold or room temp.

Because it is not clearly marked, I wouldn't assume that they are microwave safe. My Pyrex bowls are all marked safe for microwave, for example. They are rather thin, so on the plus side each piece is lightweight, but not as durable as something heavier. I guess that's the trade off.

No they are not microwave safe and they are not labeled microwave safe. In general heating plastic releases carcinogens. Microwaving with a glass pyrex measuring cup and pouring in the contents does the job well.

I don't know, I have never tried anything in the microwave, but my guess would be yes because they are very thick and durable. They do really great in the dishwasher, top or bottom shelf.

They are NOT indicated as "microwave safe" on the bowls. They are a Type 2 plastic, which is "high density polyethylene" (HDPE) = May be safe, although some recommend against food contact when microwaving. I personally do NOT use these in the microwave. They seem fine in the top rack of the dishwasher, but I wouldn't put them on the bottom rack.

I no longer own them, but as I recall they are microwave-safe. I used them to reheat food and occasionally even as a cover for other plates I would microwave.

They are only advertised as being microwave and dishwasher safe so I believe they would not be oven safe.

Yes, they are, as the Product Description states. They are dishwasher and microwave safe.

Yes they are microwave safe. I've used them a number of times there and they stay fairly cool to the touch unless you nuke the food for over six minutes. This was my second set of this style and have had the first set over ten years.

They are definitely microwave safe. They are also oven safe as long as you are not using super high heat (e.g. broiler). I put them on a baking sheet so they're easier to retrieve from the oven once they're done.

Yes, these bowls are microwave safe. We use them that way occasionally, but it does seem they heat up more than a ceramic product. Hope you enjoy them. We do and we have plates and all.

Yes, they are both dishwasher and microwave safe. I wouldn't have purchased then if they weren't.

No there is nothing stated on them about being microwave safe. Sorry I only use mine for cold stuff. Probably not a good idea to heat any plastics these days. It doesn't even say dishwasher safe??

I haven't put them in the microwave. It is made of ceramic. The bowls are small. I use it for cold food . The box does not say microwave safe

Yes they are microwave safe. Dishwasher safe. They work well in the freezer also.

I just read that they are not recommended for use in the microwave. Oops. :P

I have not microwaved them, and I do not believe they are safe for the microwave. They are very nice bowls, though!
