Definitely jar them up.
They are all great tobacco products and it would be tragic for them to be found ruined in a year or two because the bags were compromised.
Yep, I prefer to use the half pint jars and pack 2 oz per jar. I like variety so I have a lot of open blends, using the smaller jars let’s me have an open one to smoke out of and the rest can rest undisturbed.
