I started smoking pipe about 6 months ago and I definitely enjoy it. However I don't smoke too much and I like to use different tobaccos so I have the issue of how to keep fresh the tobacco once a tin is opened. I am aware the best way should be using mason jars but for space saving I prefer keeping the tobacco in the original tin. So I figure out to “reseal” in some way the tin putting a double layer aluminum foil under the cover of the tin cutting it to just protrude outside of the cover of the tin and then sealing the tin with 3M electric tape running between the cover and below the protruding aluminum foil. The good thing of electric tape is that it is malleable and it looks to give a good seal and as a matter of fact I don't detect any smell coming out of the tin. Is it an acceptable way to reseal a tin? Anybody else used this method to reseal a tin and for how long can it work?
