This section holds the Gillott 170 nib in the Pump Pen.
The Gillott 170 nib is a small flexible nib that is popular with a wide range of artists, especially illustrators and cartoonists. It is very flexible, draws a very fine hairline and provides a good variation in line width.
The Perfect Fit feed provides a flow of ink or paint to the nib, which relieves you from having to dip the nib or paint the top of the nib.
You can remove the nib when it needs to be cleaned, and you can replace the nib when it wears down or snaps.
