Anyone who writes by hand a lot knows that the same pen is usually not equally suitable for every situation: Sometimes a handy, sometimes a more solid writing instrument is required. Whether for a short note, writing longer pieces of correspondence or signing important documents - the Supra fountain pen from Kaweco, which is unmistakably related to the much smaller Kaweco model Liliput, is particularly impressive because of its wide range of uses. The pen, which consists of four parts (cap, front and rear sections, center section), can be screwed together as required, making it variable in length. In the twinkling of an eye - in this case, the twinkling of a pen - the stately fountain pen for official occasions can be transformed into a handy writing instrument for everyday use or even into a compact companion for on-the-go use that, when closed, even fits into a trouser pocket. This variable length spectrum distinguishes the Supra offered here from the smaller Liliput, as does its nib: that of the Supra is significantly larger. The nib is available in three widths, which have a significant influence on the typeface and ink consumption. To ensure that the ink never runs out, the pen can be extended by the center piece to accommodate a replacement cartridge. The cap has an internal thread; thus, it either closes the fountain pen tightly, or it extends the writing instrument.

The turned stainless steel barrel of this version of the Kaweco Supra is a special eye-catcher: although the barrel and construction are plain, the heat treatment of the surface causes it to tarnish in color, giving it its unusual appearance. How the tarnish color turns out cannot be predetermined - predominantly blue, it will nevertheless always have its own heterogeneous coloring (like the manifold of a motorcycle or moped exhaust). The appearance of each individual Kaweco Supra is thus as individual as the handwriting of its owner. By the way, tarnish colors should not be confused with so-called annealing colors, which occur when stainless steel is heated above a certain temperature: Depending on the temperature, a very specific, ergo reproducible color is produced.
