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.
Fluorescent: This ink glows under UV light.
Because Noodler's inks are hand made in small batches, the colors can vary slightly from one bottle to another.
