There are only a few writing instruments which have been successful in the market for decades without big changes. One of them is, of course, the Kaweco Classic Sport. It follows the design of the year 1935. There are several writing systems available in various color combinations. Fountain pens are available in fine, medium & broad nib with a stainless steel nib with 23 karat gold plating.
This pen is ideally sized to fit into a large wallet or small purse and its faceted barrel prevents it from rolling away. Twist-on threaded cap is another great feature
Pocket clip is available separately for purchase.
