Diamine Archival

Diamine Registrar's ink is an archival ink and is used by Registrars and the Clergy in the United Kingdom for signing official documents. It is permanent/waterproof. Registrar's ink is an iron gall based fountain pen ink; therefore, it is recommended that you flush your pen with cold water prior to refilling or before storing away. This ink when first applied looks blue and as it oxidizes it turns blue/black. A bottle of Registrar's contains 30 mL of ink. _________________________________________________ Please be aware that colour representation cannot be truly accurate owing to the reproduction on different computer systems, variations in scanning and variations in pen, paper and ink characteristics.
