The white cap and barrel ends are made of high quality resin that is first turned and then polished to a high sheen. The barrel with the white and green stripes is made of cellulose acetate that was very carefully manufactured and turned into a sleeve.
Double rings at the end of the barrel and on the cap are integrated into the material. This is done with the highest precision in order to obtain a virtually seamless transition between the materials. The fountain pen has a 14K gold nib.
The Souverän 605 Green White is encased in a specially designed gift box.
