The Faber-Castell Ondoro series is unique fountain pen. The various models of the Ondoro series are either made out of smoked oak wood or from precious resin. The barrel of the pen as well as cap are hexagonal and not round like most pens, so the first thing you notice in this design is the unusual contour of the pen. The accessories are chrome plated and complement the color of the barrel perfectly. The pen uses the standard international cartridge/ converter system and comes in various nib sizes. The nib of the pen doesn’t feature a breathing hole which is a distinctive feature of Faber-Castell pens.
The pen does not come equipped with a converter.
