I have done that, no issues. Not sure I would put Ennerdale in with a light Virginia Flake, though. ?I'm getting tired of 'decanting' the tobacco tins I buy into mason jars. Now I have 20 jars taking up space. I've read up on the problems of putting boveda packs directly into a jar (which seems completely unnecessary). But why not just put the tins (after they are opened) into a large tupperware with a few 62% boveda packs. Would allow you to keep the tobacco in the tin and control the ambient humidity.
