Single use or thinner plastic would work short term but if you are looking for something long term I would go with glass. Mason jars or even cleaned out food jars (like for pasta sauce) work perfectly.

Also, store the jars in a spot where there is as little temperature fluctuation as possible. Everyone goes for the basement, but even subtle seasonal temperature changes can affect the lifespan of stored paint.

I work in a paint store, and this is what I usually advise customers to do.

Thank you! I couldn't figure out why it always looked fine when I typed it and then showed up all weird once posted.

Great episode. I mean, they were all great. M*A*S*H was the best for easter eggs, it's a fun rabbit hole to go down if you are a fan of the show.

Also, it's a rare thing that my username is this relevant.
