We know from the papyrus rolls discovered in Egypt that writing with pen, or reed, and ink was practiced in early days. Jeremiah caused Baruch to write in a book with ink the denunciations against Israel and Judah (Jer. 36:18). The horn that contained the ink was carried in the girdle, as it is in some parts of the East to this day (Ezek. 9:2-3,11).
