Pigment Based Ink
Description

Platinum Chou Kuro may be the darkest black fountain pen ink ever created. Measuring 46.8% darker than Platinum’s renowned Carbon Black, this pigment-based formulation delivers an uncompromising matte finish that absorbs light rather than reflecting it.

Exceptional Depth
This ink achieves remarkable blackness through a unique interaction between pigment particles and the mineral content in paper. The result is a pure, condensed black with no hint of grey, blue, or purple undertones, maintaining an utterly matte surface from first stroke to last.

Permanent and Resilient
Fade-resistant and highly water-resistant once dry, Chou Kuro minimizes feathering and bleeding, making it ideal for archival documents, journals, and important correspondence.

Using this ink in a fountain pen requires careful maintenance and should not be used in valuable or sentimental pens. Read more in the ‘Good to know’ section.

Essential Care Instructions
Pigmented inks demand thoughtful maintenance, and Chou Kuro is no exception. Please observe these precautions carefully:

  1. Use distilled or purified water only for cleaning. Tap water contains minerals that react with the ink, creating deposits that can stain your pen and make removal extremely difficult. This is the single most important precaution.
  2. Keep your pen in regular use. Never allow this ink to dry completely inside your pen. If you write infrequently, consider dedicating an inexpensive pen to this ink rather than a valuable or sentimental piece.

  4. Shake the bottle before each fill to ensure pigment particles distribute evenly throughout the ink.
  5. Store properly. Keep the bottle away from direct sunlight, heat, and humidity to preserve the ink’s properties.
  6. Consider your nib size. Medium and broader nibs handle pigmented inks more reliably than extra fine points, which are more susceptible to clogging.

    If you appreciate the ritual of fountain pen writing and seek the absolute deepest black possible, Chou Kuro delivers. This ink rewards careful maintenance with unparalleled richness and permanence. Available in a 60ml glass bottle with a convenient reservoir well for easy filling.​​​​​​​​​​​​​​​​
