The Kaweco Supra is the larger version of the Kaweco Liliput and includes a sized-up #6 steel nib, as well as connecting piece that can be added to change the length of the pen by 3 cm. With the piece installed, the Supra is a full-size pen that can hold a standard international converter, one standard international long ink cartridge, or two standard international short cartridges. Without the piece installed, the Supra is about the same length as a Liliput and can hold a single standard international short cartridge.
The Supra fountain pen is made of solid, eco-brass from the Wieland Werke factory, which is especially high quality. It is untreated and will develop its own patina over time. It comes with one blue ink cartridge and a short tin gift box.
