This 50ml bottle of Sailor Sei-Boku Pigmented Blue-Black fountain pen ink is a high quality choice for the deep rich color and its fast-drying and water resistant properties. This pigmented ink was designed for brush pens, but is safe for use in fountain pens as well. A little extra care is called for, so don't leave it in your pen for weeks on end without cleaning. The pigment particles, if left to dry, can require a little more maintenance to clean out. Sailor Sei-Boku Pigmented Blue-Black fountain pen ink dries on the surface of the paper and is perfect for mixed-media or watercolor artists who use thicker sketch or watercolor paper, but this also works well for artists or others who use fountain pens, with a color wash over top.
