Me, I use on a consistent basis an empty M&M Minis plastic tube as a "travel case" for a single cigar. As long as the stogie's no longer nor fatter than a corona, this works just fine. And this is despite the fact that I own a half-dozen or so nice leather cigar cases. I can slip this tube into a shirt or hip pocket with much greater ease.
Hey, whatever works, right? I'm not likely to impress anybody anyway, so why try?
