How well do these seal? If they have a liquid in them and it falls over will it leak out or be okay?

They seal horribly. Not only will the liquid spill, the lids most likely will fall off too.

I will be putting honey in mine and I'm fairly confident that they will seal nicely. The lid is sturdy and twists very tight.

I have never had a problem with the seal. Although you don't have that little bump you have in other jars, this one is just a matter of trust. I tighten the lid really good. When I make jam and after I put the lid on, I just tighten the lid, turn the jar upside down (Inversion) and set for 5 minutes. Turn over and it is sealed. Now remember the jam is hot and would seal as would a ball lid on a jelly jar. Are you putting in a cold liquid or hot liquid? Cold may make a difference.

We use them for liquid and have had no issues with them. I have put self tanner (very liquidy), shampoo, conditioner etc, and worked out for us with no leaks.

These are leak-proof. I've packed water and milk in them for the kids' lunches and never had an issue. (Except when the preschooler threw his away and I had to dumpster dive.)

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

If you get them sealed properly they are very good at keeping a good seal. There is a little plastic tool on the front that one uses to seal with. I love mine;=.

They haven't leaked and I have stored them horizontally. Of course, just make sure the lid is properly screwed on :). These are great bottles and I love that I can grab one "to go" for a snack for baby by just screwing a nipple on instead of the cap!

They hold up very well. They will eventually spring a leak, but I have been using a pair for almost five months and they are still leak free. I use them multiple of times a day. They have a very good grip ability. Much better than the ones I've bought at the grocery store. I like them so much that I keep a spare in case a leak develops. Hope this helps.

I wouldn't risk it. They'll definitely leak eventually. They were pretty good brand new, but after a while they start to leak just laying on its side.

Yes, the seal is not tight on these containers. Unfortunately, they leak as well.

Not sure about out of the package. I hit mine with some silicone spray to seal it up even better as soon as I got them. Didn't leak on me

We own several of these and have never had one leak. They fall over in the back of vehicles while offroading and get knocked around, but as of yet, none of ours have ever leaked. As long as you seal it properly it's designed not to leak.

I have driven with them on their sides on my roof basket. They did not leak. Not extensive testing, but it seems like a good solid seal.

Yes, the seal is very thin and will not compress when the lid is screwed on. It is a novelty item only. I think it would be the luck of the draw if you got one that didn't leak.

I haven't had anything leak through when using them... They hold a lot more than you think they would.

I tested two of them to see if they are water-tight. You have to have the lid perfectly in place, otherwise they leak. I would not recommend them for transporting liquids (such as in a bag). Hwvr, they would make fine canisters for around your work space.

Yes they are leak proof. I bought mine in the Container store and it is labeled leakproof on their shelf. The store sells the 2 oz size for $1.95. I use it to carry my oily lite salad dressing to the restaurant with me and it has never leaked.

I use them to put coins in them....so far they work great for protection for the coins....haven't tried putting liquid in them....putting liquid in them and handling constantly I think they would start leaking...hope I helped......

the lids I have fit firmly in place and I'm not afraid that they would leak with fluids. I use one of mine for cucumbers with vinegar. have had it almost a year now with no problems. if they do leak you should be able to get them replaced, free of charge.
