Platinum 60 ml Classic Ink - Cassis Black
Platinum's Classic Ink series features 6 interesting colours that will darken over time. It is a water soluble ink made by blending ingredients derived from plants with iron. Due to the presence of iron particles in the ink, the writing will naturally oxidize to a darker colour within 24 hours, and it will also be resistant to light and water, great for document preservation.
This ink is formulated to be fountain pen safe.
60 ml bottle with built-in reservoir. Made in Japan.
