Sailor Pigmented - Seiboku Blue Black (50ml) Bottled Ink

Sailor's Pigmented Souboku ink is a pigmented blue ink that is safe to use in any pen. Despite the fact that Seiboku is labeled as the blue-black, the color is actually a lighter blue that Souboku. The pigmentation allows the ink to be incredibly water resistant, as well as contributes to the intense shading and sheening of the ink. As with any Sailor Ink, Sailor Seiboku flows incredibly well.

- Due to the pigment particles contained in this ink, it is recommended cleaning your fountain pen more often than you would with a dye-based ink.
