This 120ml bottle of Akkerman Dutch Masters #01 Ceruleum blauw van Vermeer fountain pen ink is a bright vibrant shade of blue, and the packaging is very distinctive. The ink bottle fills by tipping the bottle upside down so that ink flows from the large bottom section, into a small upper section. When you tip the bottle back up, a small marble rests in the neck of the bottle to divide the two sections.
