I'm about a pack a day smoker and use the Bic's. I've actually never had a problem with them. I keep two in my car, carry one in my pocket, have two in my EDC bag, several inside the house, and two or three on the table on our patio. The only thing I've ever noticed to effect them is when they are cold, or when you accidentally run them through the washing machine.... BUT THEY STILL WORK once they dry out of course!!! Wanna kill these ads? We can help!
