Kaweco Sport 12K Vintage Piston Fountain Pen

The Kaweco Sport 12K Vintage Piston Fountain Pen is a larger vintage Sport-format fountain pen with an integrated piston-filling system and a substantial 14k gold nib. This example is marked 12K and is notably larger through the nib and overall proportions than the 12G model. Craftsmanship & Design The pen follows Kaweco's historic compact Sport design language while incorporating a traditional piston mechanism for bottled ink. Its proportions and larger gold nib give it a more substantial presence than the smaller 12G. Writing Experience This example is fitted with a 14k gold Medium Stub nib. The stub grind produces natural line variation, laying down broader horizontal strokes and narrower vertical strokes for a more expressive handwritten line. Condition This pen is in excellent pre-owned condition. It is offered without its original box or papers.
