Boswell Tins...need jarring?

[deckpiper]

I immediately jar all the tobacco I buy from Seattle Pipe Club and GLPease because their tins aren't really sealed. I leave the Samuel Gawith, Hearth & Home and MacBaren because those tins are vacuum sealed. At least, that is my understanding.
I just got some Boswell tobacco for the first time. Their tins are different: all metal (not foil lined cardboard), screw on lid, taped shut.
I'm still thinking I should jar the stuff.
Thoughts?
Hard to find a picture showing the whole tin on the web. Ususally, they just show the lid. Here is one that sort of shows the metal sides of the tin.

Yeah, if you're not going to smoke them soon, those Boswell tins need jarring.
That said, I don't agree re: the Pease and SPC tins not really being sealed. The seals seem fine to me. In fact, I expect they are better sealed that the SG you mention. Certainly if escaping aroma is any indication of the seal, which I think it is....

Yeah, I was under the assumption that GL Pease and SPC tins were sealed.....if not, uh oh.

GLP and SPC are sealed, I guess?...but I didn't trust them because aren't the sides cardboard? Maybe I am wrong. I know when I open them, I'm breaking a metal seal on top, but I didn't think they had an airtight seal. Would be great to be wrong.
