Are the covers metal? I am looking for small jars to put essential oil mixed in. Can't be plastic at all.

The top are metal and the jar is glass. I personally got them to store very fine nail glitter in. I love these jars as they are very sturdy and stack nicely and I don't have to worry about any of the glitter getting out.

yes they are metal. That is exactly what I used these jars for, to mix Essential Oils (Young Living) They are absolutely perfect, make wonderful gifts. I need to order more.

Mine are plastic. They are holding up just fine though. Great popper. Have not purchased microwave popcorn since. I use coconut oil or bacon grease for my popcorn.

No problem with the plastic. Are you using pure oil? A lot of the cheap oils are cut with chemicals.

Probably. They are made of heavy paper - no metal or even plastic. The containers are like ones you use for soup to go.As someone else commented, you may want to double-check with Amazon/the manufacturer.

I don't know. If you are using them for refrigerated items, or dried,, like herbs, flavored salts, etc.that would be fine. But I don't think you can can (sterlize) with plastic lids.

It appears to be a hard plastic. I think it is advised to not put oils in a plastic water bottle, because the oils will contribute to the breakdown of the plastic, but I would think that with this diffuser it wouldn't be a problem since 1. you aren't drinking out of it, and 2. the oil/water solution doesn't sit in the diffuser as long as it would sit in a water bottle. Hope this helps!

The lids are plastic but as other people have said, they don't fit well. I ordered the set and 1 lid fit fine but the other 2 were much too loose. I returned the set.

on my container the metal is on the outside of the jar. it is lined in plastic on the inside and the metal fits on the outside of the jar, the plastic part fits inside of the glass and makes a tight fit to keep everything fresh. i am very pleased with my purchase. the glass is thick and the container is well worth the price.

No, they are plastic. It's hard to tell, just looking at it, and that has not been an issue for me (though be sure to remove the caps when rubbing off the big black letters with nail polish remover). I'm happy with this enclosure.

I agree with Alex....some kind of metal...they are not the plastic ones. I am still looking for the 1 piece metal for wide mouth jars if anyone finds them. I am using them for left over paint...what a great idea.

The inside is plastic. I use them to make tinctures, so I had to make sure that there was no cardboard on the caps.

Mine have clear plastic covers. The trays themselves are fairly sturdy, however the lids are sort of flimsy and may not last forever. They should be OK if you put them away so they won't have things set on them when you aren't using them.

The pods are also plastic. It's flexible, so that way the jars don't crack when the food expands after being frozen.

The containers are not plastic. In fact, they are a corning ware or ceramic type containers.

No no no. The essential oils are powerful and will melt the plastic. Oils do not dilute in water and when the droplets of oil make contact with the plastic, it will melt and pit the plastic.

No, solid plastic inside and out. I use these instead of the metal ring and flap after my home canning is opened...also for storage in mason jars. Very durable and dishwasher doesn't seem to break them down.
