This waterproof blue-black archival ink is a traditional iron-gall formulation and is suitable for use in all fountain pens. It will last many hundreds of years on the page. Registrar's Ink will initially write blue, then darken. Packaged in 100ml bottle. Due to the acidic nature of the iron-gall formulation it is recommended that pens are flushed through after use as a precaution against corrosion
