Kaweco Lunar Sport Collection Fountain Pens

The Kaweco Lunar Sport Collection fountain pen is a new 2026 Kaweco Sport release featuring two shimmering first-launch colors: Light Green and Shadow Green. These pocket fountain pens combine Kaweco’s compact Sport design with an iridescent finish that shifts in the light for a more dynamic, collectible look.

The first Kaweco Lunar Sport Collection release includes two colors: Light Green and Shadow Green. According to the manufacturer, these are the first two shades in the Lunar Sport series and were released on February 25, 2026.

The Kaweco Lunar Sport Light Green fountain pen is described by the manufacturer as shimmering brightly like soft moonlight. Its finish reflects light in a way that gives the pen a luminous, glowing look with a fresh spring feel.

The Kaweco Lunar Sport Shadow Green fountain pen is inspired by a fresh spring night and sprouting flower buds. The manufacturer notes that green and bronze tones shine alternately within its iridescent color change, creating exciting contrasts when the pen is moved in the light.

The Kaweco Lunar Sport fountain pen is available in Extra Fine, Fine, Medium, Broad, and Double Broad nib sizes. This range gives writers plenty of flexibility, whether they want a finer everyday writing line or a broader nib with more visual presence on the page.

Yes, one of the standout features of the Kaweco Lunar Sport fountain pen is its unscrewable 060 nib unit. Compared with Kaweco’s other plastic fountain pens, this makes it easier to replace the nib later with a different nib size or material, which is especially appealing for writers who like to customize their fountain pens.

The Kaweco Lunar Sport fountain pen uses short standard international ink cartridges. It can also be used with bottled fountain pen ink when paired with a compatible Kaweco Mini Converter designed for the compact Kaweco Sport body.

Yes, the Kaweco Lunar Sport is designed as a pocket fountain pen, making it easy to carry in a pocket, pouch, or pen case. Like other Kaweco Sport fountain pens, it is compact when capped and becomes more comfortable for longer writing sessions when posted.

As part of Kaweco’s standard range, the Kaweco Lunar Sport fountain pen is shipped in Kaweco’s black paper box. This keeps the presentation consistent with other standard Kaweco writing instruments.
