If you're looking for something to tote a few cigars around in you can look for a two or three finger holder. These usually come with or made out of cedar and are nearly crush proof.

I hope that this helps.
I've NEVER heard of or experienced that before. Are you sure this is just not another urban legend? (kind of like the "you should rotate your cigars in your humidor" one )

There's a product on the market called a "Cigar Saver" or a "Cigar Savor" or something like that which was a plastic tube with a screw top cap and a spring loaded metal part inside. This device allowed you to store a cigar that you could not finish in one sitting. You could actually place the lit cigar in the tube and close it and it would extinghish itself in a very short period of time. I had very little call for one of these, and I seem to have lost the one that was given to me as a gift years ago.

These were made out of plastic and never imparted any nasty flavor to the cigar.
