Once I open any tin I just throw it all in a mason jar so I don't have to worry about humidifying it. So all the tins that I have are still sealed, but if you count my mason jars as "open" then it is around 30 I would think.
i do the same but only have 6 right now
Happiness? A good cigar, a good meal, a good cigar and a good woman - or a bad woman; it depends on how much happiness you can handle- George Burns
