From Colorverse Korea Special Ink series, Egg Cockle is a dark reddish brown ink.
Egg Cockle is called "the aristocrat of the sea" which is harvested mainly in the Chungcheongnam-do region of Korea. In Korean, it is called a "bird clam", and it is named because the meat inside the shellfish resembles a bird's beak. It is known as a specialty of Namdang Port, Hongseong-gun, as it is in season from January to February in the West Sea tidal flat during the coldest time of the year.
