Color & Visual Character

• Color: Deep, rich black (“Kiwaguro” is often rendered as “extreme black” or “ultimate black”)

• Tone / Depth: Very dark, saturated — designed to appear intense and bold on paper.

• Shading / Variation: Minimal shading is expected in typical use (because strong black tends to mask variations), though differences may appear with very wet pens or on high?absorbency papers.

• Sheen / Shimmer: None / negligible. Kiwaguro is pigment, not ink with decorative effects. 

Performance & Features

• Pigment Technology: This ink uses ultra?fine pigment particles (a “super tiny particles pigment ink”) to minimize clogging, yet deliver permanence. 

• Flow & Behavior: Designed to behave more like dye ink in smoothness, with a comfortable writing experience. 

• Bleed / Show?through: Low bleed and minimal show?through due to pigment nature and concentrated black. 

• Water / Fade Resistance: The pigment formulation confers water resistance and light resistance (less fading) — suitable for more archival or high?value writing applications. 

• Drying Time: It can take longer than standard dye inks, especially in wetter pens or broad nibs. Users report ~100 seconds in a medium nib on Rhodia paper as a reference point. 

• Cleaning / Maintenance: Because pigment particles can deposit or settle, regular cleaning is important, especially if the pen is left idle. 

Use Cases & Suitability

• Ideal For: Documents, signatures, official writing, artistic work (sketching, line work) where permanence is desired.

• Caution: Avoid letting pigment ink dry in the feed or nib for long periods — can lead to clogging or harder cleaning.

• Pen Compatibility: Generally safe in most modern fountain pens, especially ones used regularly. Some users have used Kiwaguro in pens over many years with no issues, provided regular flushing.

• Odor / Smell: Some users note that Kiwaguro can have a light “shoe polish” or similar smell (common in some pigment inks).

Sailor Pigment Ink “Kiwaguro” – 50?mL (13?2002?220)

Introducing Sailor’s ultra?fine pigment ink, Kiwaguro — “extreme black” that combines permanence and performance. Unlike traditional dye inks, Kiwaguro uses nano?scale pigment particles that deliver deep, rich black tones while resisting bleed, fade, and water damage.

Despite its permanence, Kiwaguro is engineered for smooth writing. You get the feel of a dye ink in flow, with the durability of pigment. The carefully ground particles minimize clogging risk and maintain stable behavior in many modern fountain pen feeds.

In everyday use, Kiwaguro exhibits strong saturation and bold contrast on paper. It resists feathering and shows minimal back?side ghosting, making it ideal for both artistic and official writing. Though drying times can be longer in wetter pens or broad nibs, the payoff is a stable, lasting line.

As with all pigment inks, routine maintenance is key: flush your pen periodically, especially if it’s idle for extended periods. But used well, Kiwaguro can be a reliable, versatile ink — merging the permanence of pigment with the graceful behavior sailors expect.

Encased in a 50 mL square glass bottle (53 × 44 × 70 mm) with matching outer packaging, it’s a robust, elegant addition to any ink collection.

Whether you're crafting your finest letters, signing your works, or sketching in ink wash style, Kiwaguro stands as a black ink you can trust.
