Webake Silicone Stretch Lids 10 Pack for Regular and Wide Mouth Mason Jar, Reusable Silicone Stretch Lids(Stretched to 3.5 inch), Sealed Durable Food Storage Covers Suit for Jar, Cans, Pot

I bought these for Dollar Tree small mason jars to use for mason jar size solar lights. So the lights don't get wet in the rain and short out the lights or create rust as others have mentioned, I stretch these over the top. So to my surprise these not only fit regular mason jars but also the Oui glass yogurt jars. To test I filled a jar with some water then put a lid on, pressed the center to pushed out some air, sealed perfectly and didn't leak at all. I'm trying to stop using plastic and these are nontoxic and better for food contact. Lid is high quality, nice thickness what you'd want for your needs. It's a great product. My obstacle is making sure my husband doesn't stick a sharp object through it. I like that it has a cute smiley face on it too.

The media could not be loaded. These worked very well for cake cups I made for a beach birthday party. They traveled well and didn’t leak. No scent, no off-gassing. The color is clear/white-ish and they fit my 3” jars perfectly. They washed well afterwards and were able to be reused, again and again. You could use these to cover cans or jars. The smiley face made them cute.

These are great for narrow mouth. Technically they fit the wide mouth but popped off too easy. Easy enough to clean if you don't let them sit for days on end in the bottom of your lunch bag. Super easy to use. Mostly leak proof. I haven't had one leak, but I can see how if you're really rough with them that it could happen.

These deserve a good review.People keep throwing away all my carafe and jar lids. I desperately searched for replacement lids, but for some bizarre reason, it's impossible to find replacements - especially for glass wine carafes. I was on the verge of getting rid of them all and switching to some other kind of vessels for my iced tea, lemonade, sangria and infused waters. Something with lids so obvious and attached they could not be thrown away.And then I found these little beauties. The price seemed fair, at roughly a buck apiece, so I decided to give them a shot. I'm thrilled to say they fit on just about everything I hoped they would! Most importantlly they fit the glass carafes that come with those pringle-can-looking lids that people mistake for trash. But they also fit all my Weck jars, Ball jars, those cute little Oui yogurt jars, my ceramic ramekins, and a few random glass jars and bottles too. On most things the seal was so tight that no liquid escaped when I turned them upside down. They're easy to put on and take off, they wash up well and the silicone seems pretty durable. And if that didn't make me happy enough - they have cute little smiley faces on top! I've never felt so happy about such a mundane item, honestly.In addition to being so useful for storage of everything from fancy individual desserts to kid snacks and leftovers, they will have saved me from having to endure nasty-lidless-iced-tea or having to ditch all my drink containers! Happy Day! I just ordered another set.

These work great with regular-mouth mason jars but not at all with the wide mouths. Unfortunately, 90% of my jars are the latter. I wish I had read the reviews before ordering. The product info needs to state clearly that these only fit regular-mouth mason jars.

These are really useful to have on hand as they stretch to fit different open cans and jars so you're not wasting plastic wrap, aluminum foil, etc. I even used one to cover an open lantern outside on my patio. It's been in direct sun all summer and is still intact.

I needed covers for 4.5" ramekins and these DO fit perfectly. They are very stretch and have pull-tabs to make it easy to stretch the covers over the ramekins or other containers. They are great for covering dogfood cans, soda cans and many other items you'd want to cover. 12 of them nest together so they don't take up much space in my drawer. Easily washed. Not totally clear but clear enough to see contents.

It advertises it as for 3.5” lids. It’s more for 2.75. They keep flying off when I CAN get them to fit. I’ve spilled two cups of hot tea trying. VERY UNHAPPY!!!
