Microppose Silicone Jar Lid Cover

Cutting circles of foil works fine but it's a hassle, and after a couple of cooks, the foil gets flimsy and splits.
I thought I'd try these but was initially cautious as the diameter quoted is less than the external diameter of some of my lids which are a mix of standard Kilner discs and bands, Ball plastic lids, and some generic green ones from AliExpress. I decided to order a few to check them out and can confirm that the quoted diameter is that of the jar mouth; they fit all my lids without issues.
In use, they're great. No more squishing, folding, and spinning the jars round; just stretch them on & they're good to go.

My foil days are over… these are brill 🙌🏼
