This ink is specifically designed for dip pens, not suitable for fountain pens. It provides a rich, deep black color perfect for intricate art and illustrations. The ink is waterproof, lightfast, and resistant to fading from erasers and alcohol-based inks, making it ideal for comic and manga artists, whether coloring or working in monochrome. It comes in a carefully designed glass bottle with a bowl-shaped interior for easy access to every drop, and a sturdy, thick glass base to prevent tipping.
