Kaweco Sport rollerball grey

The Kaweco Gelroller Sport in Grey features the characteristic octagonal silhouette of the Sport line, a design that originated in the 1930s and has remained unchanged since. Capped at 10.5 cm, it fits comfortably in a shirt pocket or the end of any bag – post the cap on the rear end and it extends to 13.5 cm, sitting perfectly in your hand. The included gel refill deposits ink via a ceramic ball onto paper: smooth, consistent, and rich black even with minimal pressure. Made in Germany.

Features

• Octagonal ABS plastic body in Grey: The matt, grippy surface prevents slipping in your hand and gives the pen a cool, lightweight feel – despite solid wall thickness, barely noticeable weight during extended writing.
• Screw cap with metal emblem: The cap screws on rather than clips on – this reliably protects the refill from drying out and prevents accidental opening in your bag.
• Gel refill with ceramic ball, 0.7 mm, archival-quality: Water-based gel ink flows evenly and without interruption. The script is clear and deep black, with archival-quality ink – suitable for documents requiring long-term storage.
• Posting mechanism: Cap posted on the rear end creates a balanced pen length of 13.5 cm – for relaxed writing during longer sessions without the pen feeling top-heavy.
• G2-compatible refill: The included Kaweco gel refill in the international G2 format can be replaced with other G2 refills – gel roller or ballpoint refills from other manufacturers in this format also fit.
• Made in Germany: Manufactured in Nuremberg, at the same location for generations.

Use & Tips

• Daily companion on the go: Capped, the Sport fits into any trouser pocket without fuss. The screw cap holds reliably even in a rucksack – unlike click mechanisms that can open unintentionally.
• For left-handers: Water-based gel ink – drying time advantage over classic ballpoint refills, but not instant drying like oil-based refills. On smooth, calendered paper, the ink noticeably dries faster and smudges less.
• Journalling and bullet journalling: The 0.7 mm ceramic ball produces a consistent, legible line without pressure variation – ideal for quick notes, layouts and labelling in notebooks with ink-resistant paper.
• Refill upgrade: Those preferring a finer line can switch to a G2 gel refill in 0.5 mm. For a drier, more smudge-resistant result, an oil-based ballpoint refill in G2 format is recommended.
• Archival use: Thanks to archival-quality ink, the pen is suitable for contracts, handwritten minutes and anything requiring long-term readability.

For Pen Enthusiasts

The Kaweco Sport housing in ABS plastic is deliberately kept lightweight – not as a compromise, but so that pen weight plays no role during extended writing. The octagonal cross-section is not merely an aesthetic feature: it prevents rolling on inclined surfaces and provides the hand with three natural contact points, without needing a conventional grip section. The Kaweco gel refill uses a ceramic ball instead of a steel or tungsten carbide ball – ceramic is chemically neutral towards water-based gel ink, which eliminates corrosion at the writing tip and ensures consistent ink flow throughout the refill's lifespan. The G2-format refill is an international standard, providing access to a broad range of replacement refills from various manufacturers and line widths.
