The Graf von Faber-Castell line counts as a high-quality choice with top quality and a solid image. Since the models have a Bock feed designed for German ink manufactories, any ink from German makers can be used; as writing colour washable royal blue is recommended. As alternatives further exclusive brands like OMAS (Paragon, celluloid models) come into consideration, convincing through light natural materials and elegant finish. When trial-writing in the shop it is recommended to bring one's own paper, since the shop paper is often very smooth and distorts writing behaviour.
