Noodler's Cayenne (3oz Bottled Ink)
Noodler's Cayenne (3oz Bottled Ink)Noodler’s “Bulletproof” inks use special cellulose-reactive dyes that
make them exceptionally permanent yet still gentle on pens. They are
highly resistant to water, bleach, and other solvents, as well as UV
radiation and most other tools used by forgers and check washers. All
bulletproof inks are also “eternal”, meaning that they are fade-resistant
and archival. Other permanent fountain pen inks use either pigments or
iron gall, both of which can harm pens if allowed to dry out inside them.
Bulletproof inks don’t have that risk.
