Platinum Black Carbon Pigment Ink Bottle 60ml

This is ink is pigment based - as opposed to dye based; this means it has actual minuscule particles of coal to give it a great depth of black colour and is permanent. Watercolours and other mediums can be washed over without the ink running. 
Usually forbidden to use with fountain pens, this specially formulated ink is compatible to use with Platinum's Extra Fine Drawing and Drafting Fountain pen. We cannot recommend it more highly - it should become a daily companion for any drafter, designer or illustrator.
