From maker A Rural Pen Dyeworks “I take handguns and other firearms out of circulation, dissolve them in sulfuric acid and derive pigments from them, commonly known as Mars colors, including Mars Black, Mars Red and Mars Yellow.  As these are hand crafted, the colors may vary.  Join me in the transmutation of firearms into pigments.”

This black liquid ink is for dip pens, quills, reed pens, and brushes. Not for use with fountain pens. Color depth may vary with paper type. Each bottle is 1.75 oz of ink.
