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.
While for the longest time I had presumed the name came from the intense blue colour of this ink, or from its red sheen, it turns out Akkerman No. 5 gets its name from the pop group of the same name. A bit of an international one-hit-wonder, Shocking Blue were best known for their single “Venus.”
Akkerman’s Shocking Blue is also a modern cult classic in fountain pen circles, with it regularly being touted as a suitable replacement for the long discontinued Parker Penman Sapphire.
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.
