Porous point pen

Porous point pen

A porous point pen contains a point that is made of some porous material such as felt or ceramic.

A high quality drafting pen will usually have a ceramic tip, since this wears well and does not broaden when pressure is applied while writing. Draftsman's pens are usually fairly expensive.

For example, "Liquid Expresso" is a felt-tipped porous point pen made by PaperMate.
