Sailor’s pigmented fountain pen ink cartridges deliver exceptional durability, rich colour, and smooth performance in three distinguished shades. Designed exclusively for Sailor fountain pens, these inks are water-resistant, lightfast, and perfect for professional writing, artwork, or archival work.

Features:

• Three Exceptional Colours:
  • Kiwaguro (極黒 – Ultra Black): A deep, jet black with superb flow and a rich matte finish. We love its intense opacity, smooth writing experience, and waterproof quality—ideal for sketches, writing, and alcohol-marker-proof artwork.
  • Seiboku (青墨 – Blue-Black): A sophisticated blue-black with oceanic undertones and water resistance. Praised for its feather-free performance on any paper, it delivers a smooth, consistent flow even with fine nibs—perfect for archival writing and professional use.
  • Souboku (蒼墨 – Dark Blue): A calm, dark blue with a subtle, muted tone. Known for its water-resistant durability and smooth ink flow, it’s ideal for writers and artists who appreciate its gentle shading and refined finish.
• Water-Resistant and Lightfast: Ink dries on the paper’s surface, making it smear-proof, waterproof, and perfect for archival documents or layered artwork.
• Ultra-Fine Pigment Particles: Provides a smooth, clog-resistant flow, even with finer nibs.
• Safe for Fountain Pens: Pigmented formula requires routine cleaning (every 4-6 weeks) to maintain performance.
• Convenient Cartridges: Box of 12 proprietary Sailor cartridges ensures easy ink replacement.
• Made in Japan: Premium-quality ink trusted by professionals, writers, and artists worldwide.

Ink Care Note:
Pigmented inks contain particles that may clog pens if left to dry out. Clean your pen every 4-6 weeks or when not in use for a week or longer to ensure smooth performance.
