Diamine Registrar’s Ink Blue-Black – Waterproof Archival Fountain Pen Ink (100ml)
Description
This is the sensible, long-term option. Diamine Registrar’s Ink Blue-Black writes onto the page in a composed blue, then gradually oxidises to a permanent black as it bonds with the paper. The effect is quietly reassuring — nothing flashy, just writing that stays exactly where you put it.
Used for generations to record births, deaths and marriages, this is genuine archival-quality fountain pen ink, waterproof once dry and entirely resistant to fading, smudging or second thoughts. Supplied in a generous 100ml refill bottle, it’s ideal if you write often, sign important documents regularly, or simply dislike running out of ink at inconvenient moments.
