The Brass Kaweco Supra is the larger version of the Kaweco Liliput and includes a sized-up #6 steel nib, as well as an extender that can be added to change the length of the pen by 3 cm. With the extender installed, the Supra is a full-size pen that can hold a standard international converter or cartridge. Without the extender, the Supra fits a mini converter.
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. The Supra comes in a short tin box with a blue ink cartridge in the body of the pen, which is an international standard refill. Optional Kaweco converter and pen clip are sold separately.
