The Midnight Blue loose ink is ideal for adding a subtle blue tinge to your writing. Many individuals enjoy different colours instead of writing with black ink. The high-quality ink is designed to be fast drying to help limit the number of smudges on your page; this ink works with fountain pens that have a built-in or removable piston converter. The ink bottle embraces Montblanc's new ink shoe shape with the enamel emblem cap and refined 3 ring design lid. The bottle is made of glass so you can see the blue coloured ink inside; it comes packaged inside a small Montblanc gift box embracing the ink colour.
