'Strike anywhere' matches. Such as Swan Vestas ('The Smoker's Match'), which could be ignited by rubbing against any rough surface (such as the back of someone's neck). They were banned in the EU in 2018.
Gillette blade cases were designed to serve as match holders when empty, and had a ridged base for striking the match on. Little adverts for the blades, carried around by smokers.
While clearing out my work crap just before the first COVID lockdown, I happened upon a box of England's Glory with strike-anywhere red match heads. I kept it as a piece of history ... but now have no idea where the heck I put it.
