Masontops Tough Top Canning Jar Lid Dib-602964

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

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.

The white wasn't white - it's a light purple tinge. OK quality but not what I've come to expect from Masontops unfortunately (usually they're awesome!)

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.

Preferred to metal tops.
