What to do with these Talenti gelato jars…

Fill ’em with your spare filters!

They fit well, and have nice tight fitting lids. I put a paper towel in the bottom of each one to take up the small space between the jar and the filters.

Edited to add:

I found that these jars will hold up to mineral spirits-so if you have a oiled filter, you can drop it in the jar, fill partway with mineral spirits, screw on the lid, and shake.
