what is the grade of the plastic on the lids

It is a very heavy grade of plastic. I have dropped mine, and it hasn't broken.....even in cold temperatures! (Wyoming) I always hand wash mine as I don't like to weaken the mechanism from the dishwasher's intense heat. I would never have any other Travel Mug.

they are plastic and if I had known that I would not have purchased them....they make nice refrigerator containers.

There are not any markings on the lids or packaging that indicate the type of plastic or if they are recyclable. It is Manufactured by: Texas Best Unlimited, LP in Kerrville, TX. Toll-Free# (830)257-6020. No known website.

The put of the lid that lifts up is plastic, but the base of the lid that has the label is stainless steel

They're glass, so yes, they're "food grade" although bottles aren't classified as "food grade." I always boil both the bottles and the droppers for a few minutes in water to sterilize them.

Yes, the plastic is safe up to 230 degrees and the lids are tight and leak free. I can pry the lids off by hand because I am quite strong but it is hard. I bent my fingernail back really badly one time.

I'm not certain. I feed my dogs the blue wilderness freedom cans at 12.5 oz and these lids are very easy to put on. Hope that helps some.

They are a metal...not commercial grade. The lids are thin plastic. There are 3~ 2 1/2 Qt dishes. hold 20 ~ 4oz servings. I read all the reviews and was very hesitant on getting them. The dial did smoke, I turned it on and ran it for 10 min, turned it off let it cool and turned it on again and it was fine. They struggled keeping the food real warm, it was just warm. I ran them under hot water to heat the dishes before I put the hot food in, that helped. It did the job, not the best purchase. I hosted Thanksgiving and needed some smaller dishes, so I bought these. If you entertain a lot, I would make the investment in a better quality product. I hope this helped!

They consider the lids to be pieces which makes it 10. They also throw in 2 utensals, I cant remember which ones I got. They bring it to 12 total. I've had the set a while now and they have held up well.

Hi I would think they are oven proof glass. They do have plastic lids which would not be. I love them. The are heavy glass, easy to clean and very microwavable. I tossed all my other storage and this set is all I need.

Not sure. They are much better than the older ones. They are thicker and stain resistant. No more pasta sauce rings as I got with the older cheaper ones. Well worth the extra cost. And yes the lids are the same size as the old ones.

im not sure what the max is, but I've used them in my microwave and in the oven and they did fine. Of course, no plastic lid in the oven! lol

They are thick walled but I don't have a measurement but I have used them in a lot of different hard plastic lids and they have fit them all.

The glass lids are. I don't know about the plastic ones. I personally wouldn't use the plastic ones in the microwave.

The lids are glass with a plastic ring that seals them very tightly! Truly a quality product!

Not sure what you want for details... but it is a hard white plastic, not flimsy. I have found those lids to be really useful.

The lids are stainless steel, made from the same material as the pots. The 10 piece set is very high quality and takes up little space in my tiny trailer. I wouldn't mind having a set for my kitchen in my house as well.
