P.W. Akkerman is a pen store in The Hague, Netherlands that was founded in 1910. To celebrate their 100th Anniversary in 2010, they released a line of inks with a very distinctive ink bottle.
Named for the Avenue of the New East Indies, referring to the former Dutch colony of the “East Indies” which are now Indonesia. This is an ink that somehow rides the line between Blue-Grey and Blue-Green. With its heavy shading properties, Akkerman No. 9 is a characterful ink to say the least.
The P.W. Akkerman 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 create a reservoir, making it easy to fill the fountain pen. The P.W. Akkerman bottles contain 60mL of inks, while the name of each colour has been named after a different location in the Hague.
