Traditional Korean paper, hanji, is made from mulberry bark and is extremely durable, lating for more than a thousand years. It is no surprise that evidence of the world's oldest movable metal type print, jikjisimcheyojeol, was printed on hanji back in 1377 and still survives today. Thanks to the durability of hanji.
Korea was able to register seven of its cultural assets including the Annals of the Joseon Dynasty as a UNESCO Memory of the world.
Nowadays, hanji has become a preferred material for craftwork due to its unique texture.
