Make your notes more memorable with these pearlescent inks from De Atramentis. Formulated specifically for use with fountain pens, each bottle features metallic ink particles that give the ink a lovely iridescent effect, with excellent sheen and slight color variation when seen from different angles. All colors can be manufactured with your choice of four metallic-colored pigments, making for a wide range of possibilities. Based in Germany, De Atramentis takes its name from the term “atramentum,” which in ancient Rome referred to any black dyeing liquid, whether produced by an octopus or used by a scribe.
