I agree with the other lads, leave them in the tin.
One thing I have noticed is there is a marked improvement between a freshly opened tobacco tin and 3-6 months in a jar. I always have a bowl of a new to me blend as soon as I open the tin and there have been numerous occasions where I didn't really care for it, jarred it, then tried it again a few months later where I found I liked it a lot more.
The first 2 or 3 times I thought it must be all in my head, that a few months in a jar couldn't make that much difference but now I'm convinced it does go through some sort of change that (to my tastes) improves the flavour.
