Kuretake Fudegokochi - extra-fine brush tip pen (0,3-1,5mm) - black

This revolutionary pen - the Fudegokochi - allows for very smooth writing. Its nylon tip reacts to the pressure exerted on it by producing thinner or wider lines as a consequence. The lines may be as thin as 0,3mm or as thick as 1,5mm.
Ink level visible through transparent slit in the handle.
Aerated cap.
