Kaweco Liliput Kibri Review: A Tiny Iridescent Pocket Fountain Pen

Introduction

Some pens are engineering statements. Others are pocket companions. The Kaweco Liliput Kibri, named after the Dutch and German word for hummingbird, is firmly in the second camp. It is a very small fountain pen with a flamed, iridescent metal finish that shifts color depending on how the light hits it, and it manages to be one of the more charming pocket pens around.

It is also not without trade-offs. This is a tiny, round, clipless pen at a premium special-edition price, so it helps to know exactly what you are signing up for before buying.

First Impressions and Packaging

The unboxing experience is thoughtfully done. The box itself has an iridescent treatment that mirrors the pen inside, along with recycling instructions. The tin is slightly different from the usual, with just a hint of iridescence on it as well, which feels like a nice touch rather than an afterthought.

Inside you get a protective sleeve for the pen, a sticker, and filling instructions. It is a tidy, complete package that makes the pen feel like the special edition it is.

Design and the Iridescent Finish

The body is iridescent PVD-coated stainless steel, and the effect is the star of the show. In the right light, the color shifts from a pleasant blue-green into a deep violet. That coating is applied consistently across the top finial, cap, barrel, section, and, unusually, the nib too. Many brands skip the nib when doing this kind of flamed finish, so having it coated here is a genuine highlight.

The Liliput model itself dates back to 1908, so this is a long-running design given a modern, colorful twist. The cap carries minimal branding, keeping the look clean.

The one design caveat: the pen is completely round and smooth, which means it rolls. Leave it on a desk unattended and it can roll right off with very little encouragement.

Size and Everyday Handling

This is a genuinely tiny pen. It is smaller than a Kaweco Sport, and unposted it almost feels like a toy pen in the hand. For many writers it will simply be too small uncapped.

The good news is that the threads at the end of the barrel let you post the cap, which turns it into a decently sized and genuinely usable pen. It is never going to feel large, but posted it is comfortable enough to be fun to write with. If you plan to carry it in a pocket, expect some dings and dents over time; for a stainless steel pocket pen, that arguably just adds character.

Nib and Writing Performance

The nibs are small, roughly number-five sized steel units, available in extra fine, fine, medium, broad, and double broad. The test unit came with a double broad nib filled with Kaweco’s purple ink, and it proved to be a pleasant writer with really good flow.

Kaweco steel nibs have historically occasionally been overpolished to the point of skipping. This one did not show that issue, which is a promising sign. That said, it is a true round nib: there is very little line variation and no noticeable stub-like contrast between downstrokes and sidestrokes.

Reverse writing is possible and gets a bit finer, though it produces a slightly strange, almost railroaded feel. And as always with this kind of nib, it is not a flex nib; you can squeeze out a tiny bit of variation, but that is not what it is for.

Filling and Converters

Out of the box the pen is filled with a standard cartridge, which works fine. The catch comes with converter use. Kaweco’s small fold-away piston converter should fit, since the pen takes a standard international sized cartridge, but it is sold separately and you will need to buy it. Other converters, including small push-pull types, are reportedly too large to fit. So if you want to use bottled ink, budget for the correct converter from the start.

Things to Consider Before Buying

There are three main drawbacks worth weighing. First, the pen is clipless out of the box. A clip is available separately for €75, which solves the rolling problem, though it arguably spoils the clean aesthetics a bit.

Second, as covered above, converting the pen is a little awkward, and only Kaweco’s own small converter is a realistic option.

Third, and most importantly, this is not an affordable pen. The price sits at €129 excluding tax for a pen this size, without a converter included, and with a small nib. It is a special edition, so some price premium is expected, but it is worth calling it what it is: expensive. Buying from retailers that discount or waive tax for overseas orders can soften the sting slightly.

Buying Advice

Buy this pen if you love pocket pens, want a genuinely eye-catching finish, and appreciate the detail of a coated nib. It is at its best posted, carried daily, and appreciated as a compact special edition rather than as a value proposition. Skip it if you need a clip on everything, want easy converter flexibility, or simply want the most pen for your money.

Conclusion

The Kaweco Liliput Kibri is a beautiful, tiny pocket fountain pen with an iridescent finish that truly earns a second look, and a nib treatment that shows the brand paying attention to details other brands skip. It rolls, it is clipless, converters are a chore, and the price is high for the size. But if the hummingbird aesthetic speaks to you and you know what you are getting, it is a delightful little pen.
