Are the containers leak proof?

A little bit. It has 3 containers. If you put liquid into the smallest container, it will leak.

The lids fit snug. The dividers are deep. As far as leak proof, I'm not sure what you plan on doing with them. If closed and left upright I don't see them leaking.

No. They will leak if laid on the side. These jugs are not completely airtight.

Yes. I have made cheesecake, carrot cake, and chocolate cake in these and never had a leak. The only thing is that it takes a little longer to clean out the tiny grooves.

No not at all. In fact they are very flexable and they don't leak if they are tipped.

I fill mine up to the top and its never leaked. Also the whole container is leak proof.

These canisters do have a gel seal around the inside of the covers. As long as you keep them clean from the contents, the seal is airtight.

My experience was that they were only leak proof if they remain total upright. I had so many things leak out of them including yogurt if they fell over!

No, they would not leak. I poured a hot solution into mine & they were fine. Worked pretty great actually.

I cant promise that they are leak proof but definitely leak resistant. If you knocked one over upside down their might be some slow seepage but not much and no real mess to clean. The heavier the liquid the safer you are. Water itself might leak out but probably not soup!

I put water in one of the containers and turned it upside down several times and it didn't leak, but no guarantees. Hope that helps.

I have not experienced any leaks from the containers while toting in my lunch bag. I try to keep containers with food upright as much as possible but have emptied my bag with a container shifted on its side, etc. but have never had any spills so far (although I have only owned these for about 8 months now). I wash the lids in my dishwasher too, so I think they are designed very well.

no they are not leak proof. I had them in a box filled with essential oils. When turned on the sides oil leaked out

There is a rubber seal on the inside of the plastic lid. Some of them still leak. I certainly would not call them airtight.

I guess it depend on what you put in them if they are leak proof. I just put water in mine, screwed them together and shook them and water leaked out. If you put snacks foods, like cheerios, crackers, etc. in them they don't leak. They do screw together easily.

The containers are sealed (there's a layer of sealing rubber in between) but if you carry liquids they can leak a little between sections.

They are! I am still amazed by this - even after going through the dishwasher! I often bring soup or juicy fruit to work and it does not leak. Hope that helps!
