Red Pigment Ink Bottle
This is ink is pigment based - as opposed to dye based; this means it has actual minuscule particles of pigment to give it a great depth of 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 this technical drawing pen. We cannot recommend it more highly - it should become a daily companion for any drafter, designer or illustrator.
If left unused for a period of time the ink, which is partial to drying, may gunk up. In this case simply rinse out the feed (the front section of pen) in clear cold water and fit with a new fresh cartridge.
This pigment ink is also available in easy to load black cartridges and in bottles in sepia or Black colours.
Alternatively this ink can also be used with dip pens and brushes and is a great artist material - it is not recommended however for use with other writing implements and especially not with precious fountain pens.
