That’s an interesting idea. I hate that food storage is all randomly sized plastic crap with a plethora of lids. It’s ridiculous when someone is selling a set where every size, every lid is different. It’s ridiculous when I find a convenient size and can’t get another of that size. It’s ridiculous that you end up building an unorganizable mess of random lids. so much better to have relatively few sizes, consistently, and durable materials that don’t need to be replaced as often.

I’ve been trying to reduce my plastic usage, the plastic content of my food, and have changed storage containers to mostly glass. But it’s still a plethora of plastic lids, I still can’t get another set of same sizes, and they’ll still have to be replaced every several years because of the plastic lid
