07. Koninginnenach blue - Akkerman fountain pen ink

The Akkerman "baby long neck" bottles have a capacity of approximately 60 ml. The faceted ink bottle is characterized by the long neck that contains a glass marble.
Akkerman fountain pen ink is suitable for any type of fountain pen and available in 31 sparkling colors. The ink colors have been given names in the Hague

What makes this bottle so unique By tilting the closed ink bottle, the neck fills with ink. Upright again, the marble will fall back and prevent the ink from flowing back. This creates a reservoir with ink above the marble from which the fountain pen can easily be filled, even when the pot is almost empty..

# 7. Koninginnenach blue

Once a year we celebrate the birthday of our king in the Netherlands. We have specially named this day after the king and is therefore appropriately called: King's Day. Before Queen Beatrix stepped down, this day was called Queen's Day, with typically Dutch activities being conducted throughout the country. The night before Queensday was called Koninginne-nach.
