Are they air tight? Will yeast smell leak out?

They are air tight. I use them to store yeast and have never had a problem.

Yes, these containers do leak, they are not air tight. Great for non-liquid items however.

Hi, they were packaged very well. There was no leakage in the shipment I received. Hope that helps

Have not tried this but I would think so. They are airtight and light weight.

Yes, this is the yeast you need....... I keep mine in the refridgerator in a airtight tupperware container and have never had any problems

They are not airtight. Water will not get in. There is no seal, but the lid overlaps the side by 2 inches. The lid also fits very snug. I have used these for about 5 years now. They are very well made (good materials, heavy duty) hold up to lots of abuse and have a lot of space. I put gear I want to keep dry and safe in it and put it in the bed of my truck. I have traveled many thousand miles with these in my truck bed and never had any issues with water leakage no matter what the weather brings.

The lid on mine seals very tightly. They are definitely "air-tight". I have not tested it in water, but I would assume that yes, they are. Hope that helps :)

Not like an airtight or waterproof seal. But I am very happy with them for just storage.

Yes they are but, be warned the ones I received did not have an air tight seal on them. So they are not sterile.

They have a pretty good rubber (maybe soft plastic) seal. I don'think it's air tight. They have been dependable in storing flour and cookies.

I put flour and sugar in mine. They have rubber seals on them an as long as you make sure they are tightly closed, they work ok. I would not say they are really super air tight though.

I got two, and I feel they do become airtight if all air is taken out first, by that I mean fill complete to over fill. I use them all the time, I will if I need to buy again.

THEY ARE NOT AIRTIGHT!!!! Good for crafts or buttons I guess? The plastic seal between the metal cap and the jar is not designed to be airtight seal.

They do have rubber gaskets, but I only use mine decoratively so I haven't tried them for flour etc. Don't know if they are air tight or not.

Yes, they are airtight. I use them though for flavored water, not juicing. They do seal very well.

They screw off. Someone in the reviews said they leak. I have not had that problem.Some weeks later -- yes, I am finding they do leak a bit. I wrap the jars in a paper towel when I take them with me now.Another update: they don't leak if you make a thicker yogurt, using powdered milk along with the regular milk! If your yogurt is thinner and has that layer of whey on top, then they do leak.

I do not believe they would leak. I found that the cork was quite secure. I, however, did not put any liquid in them when I used them. Hope it works for you.
