Rust Resistant Stainless Steel Regular Mouth Storage Lids Mason Jar Caps with Reusable Silicone Seals for Transform Mason Ball Canning Jars (6 Pack, Regular Mouth)

I am not sure how this person sells these with a clear conscience. They do not seal. The only way to get the lid to actually close completely is to remove the silicon insert.....but then they aren't airtight. Don't even think about putting liquid in a mason jar with these as the lid! The lid pops off! I tried to make hot tea for transport and the lid popped off! I would be scared of legal action from someone who got burned if I were this company. Amazon should not allow these to be sold for anything but decorative use. These should be taken down unless the description is changed. These are definitely not for food storage. The positive reviews on here must be from people who got paid.

We use a lot of jars, for everything from storing leftovers, to storing our bulk dried goods, to freezing sauces. We don't even own regular drinking glasses - we only use jars. Mason jars are just so versatile, we use them for just about everything you might need a container for. Unfortunately the standard 2-piece lids that come with the jars are good for canning, but they rust terribly. We have completely stopped using the regular lids and have switched over to all stainless and plastic lids. I have ordered and/or used no less than 7 types of jar lids, and these are by far the best for anything where you want an air/water-tight seal, such as storing leftovers or packing lunch. The stainless is easy to clean and won't rust in the dishwasher. The silicon gasket seals quite well, comes right out when it is time to wash the lids, and are equally easy to put back when everything is clean and dry. I just take the gaskets out, and put both the lids and gaskets right in the dishwasher. We also use a dry-erase marker to write the date of leftovers right on the lids. While they are a little pricier than some of the plastic options (we use plastic lids for dry goods because they are cheaper), they just work so much better than anything else I have found for day-to-day use. From my experience, anything without a gasket will leak... because of the way glass jars are made, the rims are not perfect, and you need a soft gasket to conform and seal against those subtle variations in jar shape. All the plastic lids that I have tried (including ones with gaskets) were disappointing. I cannot recommend these highly enough.2020 Update:I am now ordering these for the 4th time because we keep using them for almost everything and we need more. We have been using these for a couple years now, running them through the dishwasher regularly, and they have held up well. Not sure if they are made of a 304 or 316 grade stainless, but whatever it is, neither vinegar nor salt seem to affect it. A couple of them have dents from where the jar got dropped, but they are designed in such a way that the gasket still makes a great seal, even with a dent in the corner. They are definitely more expensive than plastic lids (we use plastic lids for dry goods), but nothing else we have tried is as useful for leftovers, sauces, dressings, etc. stored in the fridge.

Edited to add: a few of days after writing this review I was going to throw the jar out and decided to give it one last try. This time the lid finally came off, but I’m still very wary of these.A couple of days ago I added some spices to a mason jar, poured in hot water, and screwed on this lid. After steeping the spices for half an hour for tea, I tried to remove the lid and it wouldn’t come off! I have tried everything I could think of, running the lid and jar under hot water, chilling it, using a jar opener, tapping the lid against the counter, but nothing worked. And there is no way to contact the manufacturer. Now I am going to have to throw away both the jar and the lid. It’s possible this was some sort of freak incident, but I’m too afraid to use any of these lids now. They’re all going in the trash.

I bought both the narrow and the wide mouth versions. They screw on just fine!I got so many compliments on these. They are very smooth and pretty.I use mason jars for stacked salads. I live in a place where things rust quickly so I like the wood lids!These are a great alternative to metal or plastic lids.I haven't tested them for use with liquids. I'm not sure they won't leak. I'll edit my review when I find out.**update** I received a response from the seller, these lids are not recommended for liquids, but the seller does sell a metal lid that will seal the jars for liquids. I have used my bamboo lids all week for salads they are great.

I have really enjoyed using these. Not having to deal with the weak rings of the standard lids for Mason jars is great. No rusting thus far.My only complaint is that the silicon sealing ring can get a little loose between uses, but this is a niggling thing and not too important.

I did a scratch test on these lids as soon as they came, and the black stays on very well. That being said, one lid did have a small scratch on it, likely from shipping jostling as the lids are touching each other in the box. Scratching at the scratch with a fingernail did not take off more black, so the color is very solidly part of the lids.As per the item description, these are designed for wide mouth ball jars and they fit perfectly. I can feel the suckering seal when I put them on the glass and it's very satisfying. A little expensive, but they function as they are supposed to... and look good doing it.

Reason for 3 stars is the silicone gasket does not stay in place and comes off easily whenever you open the bottle. Otherwise with not many one piece wide mouth metal lids available this jar lid will solve the purpose but it may not be the perfect one you wanted.

I ordered 6 packages for my dried food for use on ball caning jars. I tried one out with liquid and it sealed tight. All the lids fit well. With the rubber gasket they of course will not tighten all the way down but they do seal. Over time they will probably wear down some. I had no problem with the lids popping off as someone previously mention. I even tried to pop one off, no luck. ordering a few box boxes.

Good product but absurdly expensive at $38 Canadian. Strongly recommend you find these elsewhere, 100% markup by the importer.

The threads from the lids don’t screw on the jars properly.

Die Deckel an sich sind gut, aber statt der ausgelobten 6 Deckel kamen nur 5 an.
