Noodler's Eel Black Fountain Pen Ink, 87 ml

It is specially formulated to lubricate the pistons of piston-filled fountain pens and converters, helping them to operate more smoothly and easily.

Special Properties:

 Bulletproof: This ink is water-resistant on cellulose-based papers and resists all known tools of forgers, including UV light, bleach, alcohol, and other solvents. This ink may still be vulnerable to smearing when exposed to water.

• Eternal: Made to resist the effects of time, this ink is archival, fade-resistant, and unaffected by humid or acidic conditions.
• Lubricated: This ink is specially formulated to lubricate the pistons of piston-filled fountain pens and converters for smooth operation.
• If you like Noodler’s Black but want a lubricated ink, this is the ink for you. It’s Bulletproof, like Black, and also archival, forgery-resistant, and water-resistant. Being lubricated means it’s a better match for high-end pens with piston-filling mechanisms.
