It’s a bit different from the friction matches we commonly know today.

They made them by shaving wood thin and dipping the tips in sulfur; it could catch fire from even the smallest spark.

Of course, it lost its value once real safety matches were introduced in 1880.

Historically, there were only written descriptions, so theories about its identity and materials were all over the place.

Its true nature was finally confirmed when the one Moellendorff took from Joseon as a souvenir was discovered in Germany.
