Flacon d'encre Bleu Foncé (50 ml)

Dark Blue Fountain Pen Ink — 50 ml

The Flacon d'encre Bleu Foncé is a fifty-milliliter bottle of deep navy-toned fountain pen ink for writers who find standard bright blue insufficient in formality for the correspondence and documentation contexts they write for most regularly. Dark blue occupies a considered position in the ink color spectrum between the accessibility of bright blue and the authority of pure black — it reads as thoroughly serious and deliberate on the page without the visual sharpness of carbon black, and carries associations with executive correspondence, legal documentation, and the formal handwritten communications of professional and diplomatic tradition that still carry weight in certain contexts today.

On white paper, the ink lays down with a color that appears perceptibly deeper and more navy at full stroke coverage, revealing its full character most clearly in broad nib output where the ink deposits in greater volume per millimeter of line. In fine nibs, the shade is uniformly deep and composed. The dye-based formula is compatible with standard fountain pen systems and flows reliably through a range of nib configurations without leaving residue in the feed or requiring more frequent cleaning cycles than standard blue inks.

At fifty milliliters, this bottle provides extended supply for a writing practice that uses dark blue as its primary or sole working color. Dark blue ink is the choice for those who want their handwriting to communicate deliberateness and precision without the slightly cold impression that black can create in personal correspondence. A refined selection that signals attention to the full communicative dimension of written correspondence, from the content of the words to the color of the ink in which they appear.
