I'm thinking that I may have been unlucky and gotten a bad one. There was no pressure inside when I easily pulled the top off. It's about enough trouble to return it as to just cause me to leave it be.
So, I'll be searching the threads for tutorial "101-Smoking Mummy Dust for Beginners". It's got to be out there somewhere...
It reminds me of finding out that Tabac Manil wasn't vacuum sealed and when I opened it there was crunchiness galore. That one went into a jar immediately afterwards because I wasn't ready for that flavor.
This one will give me practice in smoking delicately and getting what I can from it.
But, I'll be checking / likely smoking this brand of square tins first. If I love it enough I suppose I would buy in bulk in the future and put it straight to jars.
I haven't had this issue with Capstan, MacBaren, or 4th Generation square tins.
I'm sure the company is frustrated with this as well, I obviously don't have an answer to provide. Hopefully they find one that works for all.
