The Kaweco Sport is a timeless favorite, combining style and function just like it did back in 1911. True to its motto, "small in the pocket, great in the hand," this Calligraphy Sport fountain pen measures a neat 4.2 inches closed and extends to a comfy 5.2 inches when the cap is posted. Plus, it includes four fun calligraphy nibs (1.1 mm, 1.5 mm, 1.9 mm, and 2.3 mm) that you can switch out anytime to mix up your writing flair.
