Glass works well but can break, if that’s an issue for your situation.
If you want transportability/ruggedness, plastic is ok.
For temp, 70 F.
For humidity, the “always works” gauge, your experienced hands will never fail.
To calibrate your hands, make a point of noticing the feel prior to smoking, and remember how well it smoked in terms of smoking damp (swells, tight draw) all the way to smoking dry (burns too hot, too fast). Way too dry will crack in your hands as you handle it. Just right burns cool and even.
IMHO, yes, tobacco is a high value commodity in both good and bad times.
Dry tobacco can be gradually brought back to the right humidity over 1-3 weeks. (Dry cigars must be introduced to humidity gradually or the wrapper will crack, i.e., it will break up in slow motion.
Tobacco lasts forever if not damaged.
You can tell that we are far removed from early America, when tobacco was commonly known to be a fine substitute for money.
Do you know is it illegal to import tobacco? I one time researched trying to get some real Turkish tobacco without success.
The best stuff I’ve found so far is pretty pricey, I LUV the Drum Halfzware Shag.
Tobacco does have its limits age-wise, as many a smoker of pre-Embargo Cuban cigars has discovered.
(Not always, though...years ago I had a chance to sample a 1905 Partagas. A remarkable experience.)
