Leonardo Momento Zero Prisma Review: A Frosted Limited Edition with a Rainbow Twist

Introduction

It takes a lot for a new fountain pen to stir genuine excitement once your tastes have settled and you know exactly what you like. The Leonardo Momento Zero Prisma is one of those rare releases that does. This limited edition retailer exclusive, available only through the Italian retailer Stilo & Stile, pairs a frosted translucent resin with rainbow PVD-coated trim in a run of just 222 pens. It is the follow-up spirit to the frosted Pura, a past Stilo & Stile exclusive that sold out almost immediately and rarely appears on the secondary market.

Who This Pen Is For

The Momento Zero Prisma is aimed at collectors who appreciate thoughtful material and finish choices rather than flashy color chasing. If you love high-quality matte finishes, subtle iridescent accents, and the playful details that limited Leonardo collaborations tend to carry, this pen deserves a close look. If you need a flex-oriented gold nib, an eyedropper-friendly body, or an always-available pen you can replace later, look elsewhere. With only 222 units and a history of similar releases selling out fast, hesitation is likely to cost you the chance to buy one at all.

Design and Materials

The body is made from the same frosted material as the Pura model, with a matte feel that grips nicely in the hand and reads as genuinely premium. The rainbow PVD coating is the defining accent: colors vary from pen to pen, and the sample here leans toward turquoise, blue, and purple. The trim is applied to the clip, the cap bands, and a band at the start of the barrel, adding color and depth without turning the pen into a full rainbow statement piece.

The cap ends in Leonardo’s traditional cone tip, angles up to the end of the clip, and transitions into those PVD-coated cap bands. The translucent cap sits on the more opaque side of the scale, which works well here: you get a glimpse of the nib inside without the converter dominating the view.

Barrel, Converter, and Ink Visibility

The barrel is straight for about an inch before tapering evenly to a cone tip at the back, mirroring the cap. It carries an engraving with the Leonardo and Stilo & Stile names plus the individual edition number. The standout detail is inside: the interior metal parts, including the portion of the section where the converter screws in, also carry the rainbow PVD treatment. Even the converter knob is coated and branded.

This matters more than it sounds. Translucent pens with converters usually show an unattractive half-empty converter, but here the visible metalwork carries the theme all the way through, making the ink window genuinely pleasant to look at. It is a touch other manufacturers would be wise to copy. The only nitpick is that a small untreated metal portion remains visible.

One practical note: this is a cartridge-converter pen that accepts standard international cartridges, but it is not recommended for eyedropper conversion. The barrel is two pieces, and the seam on the back portion may or may not be watertight. The cap twists off with a single rotation, and it posts securely. Because the cap is very light, posting does not throw off the balance.

Nib and Writing Performance

Under the cap sits a number six-sized steel nib with a rainbow finish and the Stilo & Stile logo. Steel is the only option, with sizes including extra fine, fine, medium, broad, a 1.1 stub, plus extra fine and fine flex variants. The tested medium is very smooth with low feedback and only modest line variation. Reverse writing produces a somewhat sharp, extra-extra-fine line, and the feed keeps up comfortably with fast writing.

The section uses Leonardo’s two-tier stair-step design, which transitions into the resin threads with a moderate step up to the barrel. It is comfortable in the hand, and the matte resin helps maintain a secure grip without extra pressure.

Measurements and Size Comparisons

For context, the Prisma sits comfortably alongside the frosted Pura, the Magico Tropico, and a standard Momento Zero, and runs smaller than comparators like a Sailor King of Pen or a Pelikan M1000. It feels like a classic mid-size Momento Zero in the hand, neither oversized nor pocket-sized.

The writing sample was done with Stilo & Stile’s Roman Bronze Oxidation ink, a pleasing dark emerald that closely resembles Leonardo’s Meraldo and pairs naturally with the pen’s cool-toned PVD accents.

Things to Consider Before Buying

The limits are worth stating plainly. Steel nibs only, so there is no gold upgrade path. The untested barrel seam rules out eyedroppering. The PVD colors vary between units, so you cannot pick an exact color combination. And with a limited edition of 222 pens available exclusively through Stilo & Stile, availability is the biggest constraint of all. Similar past exclusives sold out very quickly.

Buying Advice

Pricing is €/$155 for non-EU customers and $190 for EU customers who pay VAT. At $155, this is an outstanding value for a limited edition pen with this level of finish detail, coated internals included. If the frosted resin and rainbow trim appeal to you, act sooner rather than later; based on how quickly comparable Stilo & Stile exclusives have vanished, this one is unlikely to last long.

Conclusion

The Leonardo Momento Zero Prisma executes a clear design idea with unusual care: frosted matte resin, restrained rainbow accents, and PVD treatment carried into the interior hardware. Comfortable ergonomics, a smooth steel nib, secure posting, and sensible pricing round out a package that is easy to recommend, provided you move quickly and accept the steel-only nib lineup.
