Description

Diamine Blue Black Registrar Ink is a traditional iron gall fountain pen ink designed for permanence, precision, and professional use. Going down on paper as a vibrant blue, this ink gradually oxidizes to a deep, classic blue black ink shade, creating a refined and authoritative finish ideal for formal writing and official documents.

Crafted using a time-tested registrar ink formula, this permanent fountain pen ink offers excellent water resistance and archival durability. Once fully cured, the iron gall component bonds with the paper fibers, helping ensure your writing remains legible for years without significant fading. This makes it a trusted choice for record keeping, legal documentation, journaling, and signatures.

Despite its permanence, the ink provides a smooth writing experience with controlled flow and clean line definition. The elegant blue-to-blue-black transformation also adds subtle character and depth to handwriting, appealing to both professionals and fountain pen enthusiasts.

Key Features:

Iron gall ink with archival qualities
Classic blue black fountain pen ink tone
Permanent and water-resistant ink formula
Ideal for official documents and long-term records
Smooth performance in most fountain pens
