The Kaweco Lunar Sport is a pocket-sized fountain pen that when posted transforms into a full-sized pen that easily fits in your hand. This green fountain pen comes with a stainless steel nib and an ink cartridge to get you started writing right away! The Light Green shimmers brightly like soft moonlight.
 
A special highlight of this Lunar series is the unscrewable nib unit 060. Compared to our other plastic fountain pens, the nib of the Lunar fountain pen can be easily replaced with a different nib size or material afterwards.
It uses short standard international ink cartridges, or you can easily convert it to an eyedropper pen with a little bit of silicone grease. Converter and optional clip sold separately.
 
Note: This pen comes with an ink cartridge stored in the body. If it doesn’t fall right out, you can get it loose by giving the body a few solid taps on a hard surface.
