Color Bar Ink No. 29 "Blue Monday"

Just like enjoying a cocktail at a bar, this is an original ink that allows you to choose a color to suit your mood at the time.
Fill your favorite fountain pen or rollerball with a converter and enjoy the world of colored ink.

This cocktail is named "Melancholy Monday" and, unlike its languid color, has a fairly high alcohol content. This ink has an impressive color that looks like a melted mixture of blue and purple.
