Kaweco Ballpoint Pen Liliput Black

The Kaweco Liliput ballpoint in black is machined from a solid aluminium block – a three-part housing: cap, barrel, and grip section. The black anodised aluminium maintains its finish permanently; unlike brass or copper, it develops no patina but remains crisp and evenly matt-black. At 97 mm long with a slim diameter, it fits into every trouser pocket, every planner inner pocket and every small case – yet still feels cool and solid in the hand.

Features

• Solid aluminium, black anodised: The housing is machined by CNC from an aluminium block – no seam, no play. Black anodising is more scratch-resistant than lacquer and barely changes colour or feel over the years.
• Metal heart-cam mechanism: The push button operates via a metal heart-cam mechanism. The result: precise, silent extension and retraction of the refill – no clicking, no loose rattle.
• D1 refill compatibility: The Liliput works with the widely available D1 refill format. The Kaweco standard refill writes in oil-based ink in line widths of 0.8 mm, 1.0 mm and 1.2 mm (black and blue). If you prefer a different writing feel, you can use quick-drying or oil-based D1 refills from other manufacturers.
• Compact 97 mm length: Shorter than a thumb-to-little-finger span – yet still long enough to write fluidly. For planner formats like A6 or Field Notes, the proportion is ideal.
• Three-part housing: Cap, barrel and grip section – no unnecessary material, no clip included. The optional vintage clip is available separately.

Use & Tips

• Planners and notebooks: The Liliput lies flat in A5 and A6 ring binders, bullet journal covers and slim wallets. If you want a clip, you can order the Kaweco Liliput vintage clip separately.
• Changing refills: Unscrew the push button on top – the D1 refill can be pulled out directly and replaced. For a more ink-like writing feel, an oil-based D1 refill with a fine tip (0.5–0.7 mm) is recommended.
• On the go without a case: The aluminium resists scratches well. If you still want to protect the pen, the LUIBAN range has suitable Kaweco Liliput leather cases.
• Refill colour and archival quality: The included Kaweco standard refill is not archival and is not designed for ink permanence – for archive purposes, choose pigment-based D1 refills.

For Writing Instrument Enthusiasts

The Liliput series dates back to 1908 – originally made from hard rubber. Today the aluminium housing is CNC-turned from solid stock and then anodised. The heart-cam mechanism – a metal cam-lock system rather than plastic – is the key difference from cheap pocket ballpoints: it locks cleanly without springiness or chatter. The D1 format opens up a broad refill ecosystem; those who like to experiment will find both oil-based and gel-based options in this refill format with very different writing characteristics.
