Wish they were for wide mouth jars

I love the idea of these lids, however... they are SMALL.  Maybe I missed something in the description, but they only fit small mouth jars, not normal Mason jars.  So I was a bit disappointed.  I will make them work with smaller jars that I have.  Maybe they can make wide mouth Mason jars lids too.

I bought these jars to put my homemade raw milk yogurt in. They work great for this. However, the lids seem like they don't stay on too well. If they would sell these with a lid that seals better I would give the jars 5 stars.

These are fine. The only thing that would improve them would be adding a gasket to prevent them from leaking when the jar isn't standing up. They do leak kind of a lot. I would still buy them again.

Wishing they were as short as the jars.  Otherwise, really like them.

These glass weights are sized just right for a wide mouth jar.  They are made of crystal clear glass, are very smooth to the touch, and are convex on one side so as to allow the gas released during fermentation to escape (they should be placed convex side down). The weights are heavy enough to hold pretty much anything you would ferment down below a brine/liquid.

I got these for some old jars I had without seals on.  They worked great - now I just need to purchase the bigger size for my larger mouth jars.

Convenient and easy to use. They fit perfectly in a standard wide mouth jar. Pricey but nice.

great to use with any standard wide mouth jar.  It comes with very helpful directions. I have been purchasing seed from our local health food store.  They offer much more reasonable seeds than can be purchased on Amazon.

Love these lids, in fact I reordered a 6 pack. Made in USA. They fit our wide mouth glass jars, also made in USA

Really nice jars, caps look good. Only drawback is their too small to empty standard spice jar into so you have to still save leftover in old jar. Wish they were a big bigger.

These were pretty easy to use. They don't accommodate all types of jars though. At least not the ones I bought.

These lids are not for regular mouth jars as listed. We received lids that are for wide mouth jars. They are nice lids and straws. Just wrong advertised size.

I ordered 2 boxes and am very disappointed. The diameter is not as listed. Mine vary from 2 1/16 inches to 2 1/8 inches wide. Would be more suitable for standard mouth pint jars. If I use them in a wide mouth, I will have to use multiple weights, with a cover leaf underneath and even then only with large items such as  whole cucumbers. There must be some bigger and better!

These are very nice. Not for standard size mason jars. You have to purchase the jars with a large rim.

These jars are very good! They're adorable, a great size, and seem like great quality. However, the lids have a hard time staying on. Depending on what you're using these for, that may not be an issue. I, however, picked one up by the lid and got cayenne salt rub all over my Christmas tree...otherwise excellent :)

These do not fit my mason jars, but they do fit other jars i have so they did work for some jars I had.

Why did Ball stop making the rounded small-mouth half-pint jars??  These take up way too much room in the canner, so I can't process as many at a time.  And for whatever reason, over half of these jars failed to seal after my first try at processing them--way more than the rounded small-mouth jars I used for the same batch of jam.  And they cost more!!
