This pen is a great instrument for writing, but also for drawing. The nib is very smooth and rigid, it does not admit line changes, but it writes perfectly inverted, so two types of lines are obtained with two different widths, the first with about 0.5 mm and the second with about 0.3 mm. The ink used in the drawing is Diamine Ancient Cooper, quite fluid and which works perfectly with this pen. The price of this instrument is incredible for its quality.
Works Nice. It is a good pen.
