A 25ml glass bottle of Blackstone Barrister Blue Black. Blackstone Barrister Blue Black is a waterproof black color.
Blackstone Barrister inks are well behaved, saturated, waterproof, permanent fountain pen inks made in Australia by Blackstone Ink. Barrister inks are 100% waterproof and are unaffected by complete immersion in water. They are fade resistant and highly resistive to bleach, alcohol and mild acids.
Barrister inks are nano pigment inks made with sub-micron sized pigment particles instead of the usual soluble dyes. These nano particles are so small that they can easily pass through fountain pen feeds and are treated with a special soluble polymer to overcome their natural attraction to each other.
