Got these with a pack of cigarette lighters. Absolutely nothing else in the packet, no instructions. Any ideas on what they are? They are small and plastic with a piece of plastic inside with no hole in it, almost like a plug or a stopper or some kind.

A: You can keep the cig in your mouth without smoke going in to your nose and eyes, so hands free. I used one at home when I smoked in my 20s. I wouldn’t want to be seen at the bar with one though.
