Wow! The overwhelming sense of entitlement and the surety of the amateur has really stunk up this thread. Yes the tins are not good for long term storage, and square and rectangular metal tins have been a coin flip for decades. Compared to the tins made 30 years ago these are like tin foil. And it's not just tins but a general lowering of quality across a lot of industries and services.
When you get your tins, smoke them, jar them, pack them in Mylar. You're good to go. You're not entitled to multi-generational packing. If it's smokeable when you buy it off the shelf, you have no legit complaint, just unrequited self entitlement.
There's no sound reason to keep it in the tin. You'll "interrupt" the aging process? Precisely how will the results be changed? Don't know? Not surprised.
On the other hand, if you're intending to keep it in the tin for future screwing over, gouging, profiting in the "vintage" tobacco market, it's not the manufacturer's job to underwrite your enterprise.
As far as the various and occasionally heated and passionate expressions made here, they are made by people NOT IN THE ROOM WHEN EVENTS ARE HAPPENING, and are, however passionate, nothing more than opinions, not facts. Moreover, pulling a relatively low percentage of complaints from the total amount and generalizing it is a popular tactic in media and in politics. It's easy to do, takes little effort, and is widely accepted at face value by people lacking the "pause and examine" mental button. It's also misleading. People who are satisfied rarely post to say how much they like the packaging.
It's popular to imagine oneself as all knowing and all seeing, Master Of The Universe, without having done the work. It's also BS. But if you disagree, prove it by having your tree surgeon operate on your child, or on you if you value yourself more.
