AOZITA WIDE Mouth Mason Jar Lids [16 Pack] for Ball, Kerr and More - White Plastic Storage Caps for Mason/Canning Jars - Leak-Proof

Just a flat surface interior. No ridge to aid in sealing. There are much better lids out there. But they will do for now.

works perfectly.

I needed some lids for my mason jars, so I got this pack of 16 wide mouth plastic lids. They are about the same thickness and quality of the famous brands I have, but a third of the price. The only difference is that the rubber seal is not built into the lid. It comes loose, so you lay it in if you want a rubber seal. But it seals fine without the seal for me just sealing up extra soups,etc. to put in the fridge. But you can make it totally waterproof by putting in the rubber seal (included). They screw on perfectly and feel as durable as you can make them, and easy to wash up an reuse like new hundreds of times. And you get a lot more lids for a lot less price than the other brands I shopped for.

Fits perfect with my mason jars

Threading isn’t fantastic, so putting lids on can be annoying at times.
