Masontops Tough Tops - Wide Mouth Mason Jar Lid - White - BPA-Free Plastic Screw Caps - Reusable Airtight Storage Covers

Work well, really useful, just need replaceable gasket for them.

These also fit the wide mouth 'Ball' jars, which I guess is the UK brand equivalent to Mason jars. They could be a little cheaper considering they are just 4 bits of plastic and silicon. But I've already wasted a bunch of money on other lids which were utterly useless, so it's hard to grumble about the price too much

Does the job. Seem to be leak proof. My only advice would be try not to over tighten them because they can be a bugger to undo, such is the firm leak proof seal. Might not be brilliant if you have manual dexterity issues, which thankfully I don’t. Pleased with them.

I bought these for my Mason and Kilner Wide Mouth Jars, as the metal ones that came with the jars started rusting. These Wide Mouth Screw Caps are amazing. They are sturdy and fit perfectly! These also come in a smaller diameter and as a Screw Ring.

Preferred to metal tops.

Despite being clearly stated in the description of the product, these lids DO NOT FIT the quart size wide mouth Ball mason jars. Amazon even promotes these lids as a package deal with the quart Ball mason jars, but they simply do not fit, they are too big. They only fit the largest size mason jars. Very disappointed and I would definitely return, but the cost and bother are not worth it.

The ones with silicone o rings are better

fits perfect.

I’ve tried a few different lids for Mason jars, these are the best. The fit is perfect, the integrated silicone gasket works perfectly, the flats give fantastic grip, and no sharp edges. I have both regular and wide mouth lids. THE BEST.

Nice, secure fit to seal my wide mouth jars

Great for what I need it for! No more rusting. Recommend.

Love these. Easy to manipulate, with the ergonomically correct notches that fit nicely between the fingers.
