As the felt-tip pen gained more and more acceptance, an increasing number of specialised product variants became part of the commercial assortment.
The consumer realised that fibre pens could be conveniently used to mark text passages in all kinds of publications.
The tip design and inks of the fibre pens were then adapted to various application purposes. The "Marker & Highlighter" was born.
As the name indicates, this product is better suited for marking rather than writing.
