So I bought some relatively cheap glass jars that I thought had a pretty good seal... However when I walk past the area I get the delightful smell of the tobacco... Does this mean the jars are not as air tight as I had hoped? I also found some mason jars while cleaning my room, however I really don't have enough tobacco to justify using them. Any recommendations on maybe improving the seal or maybe a better way of storing small amounts (about a 50g tins worth) of tobacco.
