The 'Tightpac' Cigarette Holders made of polypropylene are so strong that it takes a car to run over them, to break them! This is what makes them different. They are so tight that you can put a burning cigarette inside, close it with the cap and it goes out immediately. Relight it again and it tastes much better than when stored in an ash tray or some other place.
