BBQ Lighters

I had a scare with strike-anywheres way back in the '80s. I bought a pack of two boxes for my boat and when I used up the first box I opened the plastic wrapping around the second box and found that the heads were all burned up. All of them. I don't know if it happened before I got them or happened slamming around in my boat but the fact is that strike-anywhere did and I can only figure that the sealed packaging snuffed the fire after the initial flare.
