I just leave them in the box. It’s oxygen that makes things deteriorate so if the oxygen is kept down, it should be a problem.
Also, when I buy lids, I date the box with the purchase year and constantly rotate my stock. Never had a problem with them.
“It’s oxygen that makes things deteriorate”
I thought about putting them in mylar with an oxygen absorber, but then I realized it would take a lot of space to store it. Unless I’m putting fine grains in mylar, it’s not a very compact package.
What are the oldest that you have used your lids and they still work?

I was wondering if a “Food Saver”, or a vacuum process would add to the longevity of the rubber ring and prevent oxidation ?
