The 0.5mm nib makes Marabu Fineliners perfect for all kinds of pen work: tangles, doodles, sketches, and more. Available in a wide range of colors, these light-fast, water based pens contain pigment based ink that's permanent when dry, making them a great choice for sketching your base layer before adding color with the Aqua Pens or Inks.
The Skyline set includes these colors: Ruby Red, Dark Ultramarine, Dark Green, and Black.
