Leonardo Momento Zero Review: A Jade Resin Beauty With a Forgiving Elastic Nib

Introduction

The Leonardo Momento Zero is one of those fountain pen models that tends to earn repeat owners, and after spending time with this jade resin version it is easy to see why. It pairs a full-size, comfortable body with a genuinely special nib option: a steel extra fine elastic nib that snaps back like a spring and produces beautiful line variation with only the lightest pressure.

First Impressions: The Jade Finish

The packaging is simple and consistent, a basic clamshell box with the pen sitting securely inside. The pen is numbered rather than limited, which is a nice touch for collectors without inflating the price or scarcity.

The jade finish is the star of the show. It is a resin with flecks of darker green, light green, ambery tones and just hints of white, and it is captured beautifully in person. The Momento Zero shape itself is part of the appeal: conical tops that are rounded rather than flat or fully round, a functional clip with a small roll-stop ball, and three rings on the center band.

The size is a sweet spot. It is a full-size pen that is not overly thick, light and comfortable in hand, and it sits just right without needing to be posted. If you do prefer posting, it posts beautifully, a little long but not heavy, which makes it friendly for larger hands as well.

Cartridge Converter and Daily Handling

The Momento Zero is a cartridge converter pen, and the included converter is threaded, so it should be unscrewed rather than yanked out. Leonardo’s converter is a nice piece in its own right, with the brand name printed on the reservoir.

The step up to the barrel has a smooth ring, the threads are smooth, and the whole pen feels comfortable rather than slippery. Compared against common benchmarks like a Pilot Metropolitan or a Lamy Safari, it reads as a nicely proportioned full-size pen.

Writing Experience and Ink Flow

Out of the pen, the flow is well tuned. It is not gushing wet, which you would not expect from an extra fine anyway, but it is also not scratchy dry. Even for someone who normally prefers juicy, wide nibs, the flow here is satisfying.

With no pressure applied, the nib writes a genuinely extra fine line. That is somewhat surprising for a western nib, which often runs broader, and the resulting line is precise and clean.

The Steel Elastic Extra Fine Nib

This is where the pen becomes special. The steel extra fine elastic nib has elastic cutouts and a plastic feed, and it lives up to the name: the tine flex snaps back like an elastic band.

Steel is a little stiffer than the gold elastic option, and that stiffness is actually a feature here. It holds up better under pressure and is far more forgiving, which makes it a great entry point for anyone with a heavier hand or anyone unfamiliar with flexible and bouncy nibs.

Under gentle pressure, the nib produces fantastic line variation, especially on loops and downstrokes. Pushing much beyond a moderate flex risks outpacing the ink flow, so restraint pays off. In everyday use, it also doubles as a lovely scripty nib for letters and light flourishes, with pleasant shading from a good ink.

Buying Advice

This particular configuration is priced at 178 euros, while the gold nib version is 398 euros. For anyone curious about elastic nibs, the steel version is the more approachable and forgiving starting point.

If jade is not your color, the Momento Zero line comes in many other finishes that are equally outstanding. As a dependable, good-looking, comfortable daily writer, it is easy to recommend, and it is the kind of model that justifies owning more than one.

Conclusion

The Leonardo Momento Zero in jade resin combines a lovely material, a perfectly sized body, and a steel extra fine elastic nib that makes expressive writing accessible. For writers who want a reliable and beautiful pen with a touch of flex, it is an easy recommendation.
