Sorry, I quit about 14 years ago when a cigarette got in the way of something I kept putting off until I finished this one, and lit the next one out of habit, got disgusted with myself, and through away what was left in the pack and 1/2 a carton. I then put all my Zippos in a drawer and a can of lighter fluid and pack of flint in a cabinet, never to be missed again. P.S. I was smoking 4 packs a day at that time.
