Sailor pigment ink cartridges are designed for compatible Sailor fountain pens. Their ultra-fine pigment ink offers smooth writing while being water-resistant. Less prone to smudging and bleed-through, it is suitable for note-taking, illustration, and documents that require long-lasting durability.

Each box contains 12 ready-to-use cartridges. Three colors are available: Kiwaguro, a deep black, Seiboku, a blue-black, and Souboku, a dark blue. The color displayed on screen may differ slightly from the actual rendering depending on the medium and display settings.
