Shimmering blue-green luster makes for a brilliant Kaweco Art Sport fountain pen known as "metallic turquoise." Our preowned pen is also like new and/or new old stock. If it was used, it was only used once or twice. It looks stunning. These are limited edition pens no longer in production. You only fill it with short standard international cartridges. The neat thing about this steel nib is that is can be unscrewed and replaced with other point sizes from Kaweco. Kinda like old Esterbrooks or modern Pelikan, even though it won't fit their nibs. You will write an extra-fine line with this one. Minimal, if any, wear. 10.1cm capped.
