Ziller Ink - Cardinal Red (28ml / 1oz)
Ziller Inks are acrylic based and made from very finely ground pigments. They flow well with both pointed and edged nibs.
They are light-fast, waterproof and Ph-balanced for archival stability.
Because the ink is bottled in a wide neck jar, an Oblique Pen Holder and nib can be easily used with it.
Clean nibs and brushes immediately after use.
