"Orange Above" fountain pen ink made by P.W. Akkerman pen store in The Hague.
A true orange, this is a vibrant ink with good shading.
Originally made to celebrate their 100th anniversary, this ink comes in a vintage-style bottle with a narrow neck with a marble stopper, to create a well at the top to aid in filling pens.
"Oranje Boven" is a Dutch folk song about the bond between the people of the Netherlands and the Dutch Royal Family. Ackerman
