Hey guys, so I am as new to pipe smoking as it gets... started two days ago and I apologise if this has been asked. I bought three flavours of tobacco and have stored them in Mason jars... the tobacco store also gave me these tube like humidifiers that I have to soak and insert into the jars. Do these work? What else should I know about keepin tobacco fresh. Looking forward to being part of the community. Joining my father and more interesting people in this relaxing ritual. Thanks so much guys and a shout out from South Africa!
