Piston filled fountain pen with a special soft semi flexible 'Maru' or 'mapping pen' nib.
This stainless steel nib gives a fine line for drawing detail but is also semi-flexible so you can draw thin or thick lines depending on the pressure. It flexes from extra-fine to medium.
The nib can be user-replaced with spare nibs available as an option.

This is a specialised pen for artwork, calligraphy and Manga. Unlike writing pens, the nib wears down and will eventually need replacing.

This piston filled pen holds a large amount of ink. To fill the pen, just put the nib in ink and twist the end. There is a click when full.

Transparent body let's you see the amount of ink left and it's colour.
This pen is not suitable for cartridges, use with bottled ink only. The hooded nib makes filling possible even when there is a small amount of ink left in the bottle.
Inkursive pens logo on cap.
Screw-on cap with sturdy clip keeps the pen secure.
There is no ink included. Use fountain pen ink.
The nib is not tipped so use on smooth paper only, this is intended for art and calligraphy, not ideal for everyday writing.

You can buy in a foam-lined metal display box or recyclable board box.
