Emma, Frieda, Vroni and Thea: these are just a few of the names of the self-confident ladies on the SketchInk ink bottles from Rohrer & Klingner. Some say provocative and sexist, others frivolous and courageous. We ourselves are not quite in agreement yet, but would think it would be good if not only women were to be seen on the labels...
SketchInk is a waterproof and light-resistant ink for your fountain pen with piston mechanism or converter. It dries quickly, so your sketches can be painted over after a short time, e.g., with watercolors. In addition to fountain pens and nibs, you can also apply the finely pigmented ink with a brush and a little water. Perfect characteristics for urban sketchers, but also for graphic artists, architects, and designers.
Because SketchInk ink is waterproof, it's possible your fountain pen dries up. That's quickly fixed with Rohrer & Klingner cleaner.
By the way: The Rohrer & Klingner Erka Rapid ink bottle fits on the 50 ml ink container: a practical insert for clean refilling of your converter or piston filler, but also for easier dipping with the drawing pen.
