Archival India Ink

Sourced from a 130-year-old formulation refined across four generations of master ink smiths in Osaka. The lampblack pigment is ground to sub-micron particle size, producing a depth of black that photographers describe as "light-absorbing." The shellac binder cures water-resistant within 4 minutes on hot-press paper and 7 minutes on cold-press. Permanently archival by ISO 11798 standards. Compatible with technical pens, dip nibs, and ruling pens.
