Black Rust Proof and Air Tight Aluminum One Piece Storage Lid with Silicone Sealing Linear Plastisol for Regular Mouth Transform Mason Ball Canning Jars (6 Pack, Regular Mouth)

These are very good quality mason jar lids. I like that they are food grade stainless steel. That makes a big difference to me that they are safe to use and safe to touch food items, especially if the food is hot soup or anything hot. They fit well and look great! Makes my pantry look more organized with nice looking jars.

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.

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.

i love these...i got rid of all my 2 piece lids. i don't can so just wanted regular lids. these are great & i love the look of the matte black. i ordered more so i can just replace all the jars with these same lids. they all just look so much nicer etc in the cabinets or fridge etcit's the little things sometimes ...

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.

These lids are fine, but I do have to be MUCH more careful how I screw the lids on. A few times I thought they were screwed securely but I didn't do a "check" (lift upside down) and they leaked a little. They work perfectly well, but only if you screw them just so and check them!

The media could not be loaded. My hubby and I made a Mason jar light fixture and I wanted black lids, these worked perfectly. We were able to cut a circle to make the fitting we needed and the paint stayed on without chipping. Very happy with the results. I will repurchase from this company again, shipping was very speedy as well.

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.
