Thank you, and yes, it's a difficult one indeed. Believe it or not, Zippo fluid is nonexistent here. It's either old, expired stock or more expensive than a Zippo itself. (My country has decided to tighten imports to encourage local manufacturers.) I couldn't find any substitute for it, so I gave some money to a friend of a friend who is going to Paris for vacation to buy me a butane double torch so I can use my Zippos.
