The shaft and cap are made of sterling silver. The fountain pens have a unusually large, high-quality gold nib. The characteristic spring clip has been further refined for design07. A special highlight: the finely worked thread guilloché on the shaft and cap.
Shaft and cap are made of solid brass and then platinized. Here again the shaft and cap have especially finely worked thread guilloché. A double coat of black translucent lacquer is followed by seven clear coats. Ground multiple times and polished by hand. Both variants are available as a fountain pen and a roller ball pen.
