Noodler's Ink Bottle (X-Feather Black - 475 ML) 19834 is a large bottle of ink from the American ink company Noodler's
It even resists feathering on very absorbent recycled paper! It is thicker than the standard Noodler's Black ink and takes longer to dry.
In addition to improving feather-resistance, this thicker formula also makes X-Feather a great choice for achieving solid, non-shading lines with flexible and italic calligraphy pens.
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.
Made to resist the effects of time, this ink is archival, fade resistant, and unaffected by humid or acidic conditions.
