Hans Heger's book 'Füllhalter für Kenner' was supplied in the writing-instrument box of the Lamy Lady: buyers could send in an enclosed request card and receive the volume free from Lamy. With high technical background knowledge Heger vividly explains the construction and function of a fountain pen, illustrated throughout with the Lamy product range. The central idea is that a fountain pen is more than a writing instrument — it reacts to individual handwriting and combines highly developed technology with traditional craftsmanship.
The book is divided into chapters on the history of the fountain pen, design, materials, the nib and its manufacture, filling systems, the feed, the writing test, the grip section, the clip, fountain-pen ink, and care and maintenance; a bibliography concludes the work. Numerous photos and schematic illustrations supplement the text.
