Ive got a terrible habit of smoking numeroues blends on the go, and I am now beginning to appreciate the difference in taste after the tin has been opened for a few weeks. Now my question is, am I in anyway risking a negative effect by leaving them in the tins once the vacum has been broken, I imagine the round tins (currently smoking Rattrays Terry Red and Petersons Irish Oak) keep better as they have a internal plastic/rubber seal that helps presumably, but I find the Peterson University Flake tin dosnt seem to seal to well. I also have a number of loose bought tobacco's stored in old tobacco tins. Just wanted peoples views on the matter.
