Platinum Classic Ink is an iron gall formulation for modern use. It has many of the desirable qualities of traditional iron gall inks, including better permanence than dye-based inks and a beautiful darkening effect while drying. Forest Black starts out a bright viridian and dries to a dark gray-green hue. Unlike traditional iron gall inks, Platinum Classic Ink is less corrosive and safer to use with your favorite pens.
The 60 mL bottle has a built-in reservoir that holds ink closer to the mouth of the bottle. Turn it over and the reservoir fills, so you can easily fill your pen even when the bottle is almost empty. Made in Japan.
