J Herbin Fountain Pen Ink Bottle — Bleu Azur : Azure Blue

Bleu Azur — Azure Blue — is a bright, clean blue with the cheerful confidence of a cloudless sky. It’s the kind of ink that makes everyday notes feel a little more alive and correspondence a touch more vivid.

From J. Herbin, the world’s oldest ink manufacturer — established in Paris in 1670 — this 30ml bottle holds water-based, pH-neutral ink made with all-natural dyes. It flows smoothly through any fountain pen, dries quickly, and won’t clog even the finest nibs. The elegant glass bottle includes a built-in pen rest, because even small courtesies matter.

Small Details, Big Difference

Smooth, reliable flow: The finely filtered ink writes cleanly from the first stroke, with no skipping or feathering on good paper.

Natural dyes, neutral pH: Gentle on pens old and new, with lightfast colour that stays true over time.

Built-in pen rest: The bottle’s design holds your pen while you write — a thoughtful detail for desk-side refilling.
