Help Airtight container recommendations for SN storage?

[heavyeyes]

I have 3 small bags of SN that I'd like to store in an airtight container to preserve their purity. I won't be taking the SN out of the bags just putting the bags inside the container if that makes sense. Will any airtight container be ok or is there a specific one I should look for? I'd like recommendations preferably for something I can find on Amazon because it's easiest to order from there.

Any sealed tub or jar should be fine, like a jam jar, or mason jar, the smaller the better
