Noodler's Ink is 100% made in the USA from cap to glass to ink. Archival quality inks in large 3oz. bottles for vintage or new fountain pens. This color is the result to replicate 1970's era mercurochrome antiseptic - famous for the bright orange/pink/red fire-like tones. When used with a brush, heavier applications dry into sepia highlights. Fluorescent under some UV wavelengths.
