This organic brown-coloured ink has been designed by Caran d'Ache as part of the Chromatics collection. Brown ink is a great alternative to blue or black ink. Brown ink is a fun pop of colour whilst maintaining levels of sophistication. This 50ml Caran d'Ache ink can be used with fountain pens with a built-in or removable piston function. This organic brown ink has been encased in a hexagonal glass bottle inspired by the Prism.
