Van Dieman's Bass Strait Cobalt Blue is a deep and stormy ink, with much to say about the treacherous waves that separate the two islands of this southern land. The Bass Strait, with a dark and tumultuous reputation, gives its hue to this ink, which is somewhat darker and deeper than most blues, with even a hint of indigo-violet. Guaranteed not to clog or clot, you will be very happy with this salty little bottle of turbulence.
