Kaweco was founded in Heidelberg, Germany in the 1890s. The Kaweco Sport Pen was developed in the mid-20s as a pen for ladies, officers and sportspersons. The Sport was suited to sport, service and social dress, due to its compact size and ability to tuck conveniently into a pocket. I carry one, it looks very professional and I feel like a reporter on a North African adventure in the 1920s, tossing my hair back, wiping the imaginary sweat off my brow, taking out my pen. It is endlessly refillable with standard ink cartridges. Less waste is good stuff! Each pen comes with one blue ink cartridge, insert and puncture the cartridge when you get the pen. Ink refills can be purchased at any respectable stationary supply and some oddball shops.
