The pocket ashtray is a snap-closing vinyl pouch that extinguishes cigarettes and holds them. Just lift the flap, pinch the sides to open the foil-lined pocket, and drop your finished cigarette in, still lit. Fold the flap and snap it shut. In moments your cigarette goes out, while its odor is locked inside. You can empty the Living the RV Life pocket ashtray safely in the next receptacle you come across, and use it again and again. The pocket ashtray will hold three or four standard cigarette butts at a time.
