Alternatives to mason jars

So far, I've been using 1 litre Kilner jars with flipped inner lids for prepping my grain spawn. These are the only ones I can get where I live that have two piece lids (I'd really like to avoid lid modifications).

I've got an eye on the IKEA Korkan 1 litre jars (

https://www.ikea.com/us/en/p/korken-jar-with-lid-clear-glass-90227985/). They don't have two piece lids, but instead a clip top with a rubber/silicone gasket.

Do you guys think it's a good idea to use these with the gaskets removed instead of the ones I use? They're half the price for me and seem to be more "tapered" too which might mean I can possibly fit two of them in my instant pot, effectively doubling my rate of prepping grain spawn!

Or do you have any better alternatives in mind? (I'd really like to avoid permanent lid modification)
