The faceted ink bottle is characterised by the long neck containing a glass marble. Akkerman fountain pen ink is suitable for any type of fountain pen and available in 31 sparkling colours. The ink colours have been given names with a Hague twist

What makes this bottle so unique? By tilting the closed ink bottle, the neck fills with ink. Set upright again, the marble falls back and prevents the ink from flowing back. This creates a reservoir of ink above the marble, from which the fountain pen can be filled easily, even when the bottle is almost empty.

#11. Treves-Turquoise

The Trêves Room is a historic meeting room from 1697 and is considered the most beautiful room in the Binnenhof, and owes its name to the French word for truce: Trêveszaal; every Friday, cabinet meetings are held here at a long table with the prime minister seated in the middle. Trêveszaal-turquoise is one of the most beautiful colours between blue and green and stands for refreshment, reliability, and effectiveness.
