Sailor Pigment Fountain Pen Ink 50ml

Sailor 50ml Archival Nano-Pigment Fountain Pen Ink

Formulated by Sailor ink chemists in Japan, this 50ml bottled ink series utilizes micro-ground nano-pigment technology to deliver absolute permanence without compromising fountain pen reliability. Unlike conventional dye-based formulas that feather or wash away under moisture, Sailor pigment ink settles securely into paper fibers to create water-insoluble, lightfast, and document-proof lines. Available in three iconic shades—deep Kiwaguro (Ultra Black), vibrant Seiboku (Blue), and understated Souboku (Blue Black)—each bottle brings archival security to fountain pens, dip pens, and illustration tools alike.

Key Features

• Archival Permanence: Micro-pigment formulation bonds permanently to paper, delivering complete waterproof, smudge-resistant, and lightfast results suitable for legal contracts, address labels, and watercolor line art.
• Anti-Clog Nano-Particle Chemistry: Ultra-fine suspended pigment particles flow smoothly through standard and fine fountain pen feeds, minimizing feathering and bleed-through even on absorbent paper.
• Quick-Drying Performance: Fast capillary absorption reduces wet-edge smearing for left-handed writers, rapid note-takers, and everyday office documentation.
• Integrated Ink Reservoir: The heavy-base 50ml square glass bottle includes an internal cone-shaped reservoir that concentrates remaining ink for clean, complete converter fills when the bottle runs low.
• Three Classic Japanese Colorways: Choose between deep matte-graphite Kiwaguro, rich shading Seiboku blue, and sophisticated muted Souboku blue-black.

Frequently Asked Questions

Q: Will pigment ink clog my fountain pen?
A: Sailor nano-pigment ink is specifically engineered for fountain pen use with ultra-fine sub-micron particles that maintain smooth capillary flow. However, because pigment particles dry permanently, we recommend capping your pen when not in use and flushing the feed with cool water every 4 to 6 weeks.

Q: Can this ink be used under watercolor or alcohol markers?
A: Yes. Once completely dry, Sailor nano-pigment ink becomes fully waterproof, making it a favorite among urban sketchers and comic artists for crisp linework that will not bleed under wet watercolor washes.

Q: How does the built-in bottle reservoir work?
A: Before unscrewing the cap, turn the closed bottle upside down and back upright once. The internal plastic cup captures ink at the top of the bottle neck, providing a deep filling well for your pen nib even when only a small amount of ink remains.

Q: What is the store's customer service and refund policy?
A: Customer inquiries are handled post-order via our dedicated service email at szjyf@outlook.com. You can request a full refund anytime before your order's shipment is confirmed.
