Ebony is used for the barrels of the Classic writing instruments in the Graf von Faber-Castell Collection.
The ebony used in the collection is sourced from Madagascar. Ebony is matte black in color, and is a very hard, dense wood. It can contain isolated small, reddish-brown grains, which are not a quality flaw, but instead a clear feature of a natural material.
The need for ebony is limited, as the wood is predominantly used in the making of musical instruments (e.g. for piano keys). In this case too, the writing instruments in the Graf von Faber-Castell Collection use wood that is too small for the making of musical instruments.
