Narwhal Horizon Twilight Review: A Nature-Inspired Piston Filler With Real Character

Introduction

Narwhal’s Horizon series takes its cues from the horizon at different times of day, with four pens in the lineup: dawn, twilight, dusk, and aurora. The Twilight version reviewed here arrives in a custom presentation box with four vertical panels depicting the four horizon states, plus a one-page use and care guide. The Horizon line is widely available at retailers and sells for $168, which feels like a fair price for a well-built piston filler with a custom resin.

First Impressions and Resin

The Horizon Twilight is a bit on the thin side with a cigar shape, and the resin is the star of the show. It’s created by Starry Night Resins, a brand run by Elise Longazel, who produces custom resins for a number of pen makers. This particular mix pairs pearlescent white with opalescent greens, and like any custom resin, no two pens will look the same.

There are genuinely nice touches in the swirl, including a subtle vein line and small spots of brown. The cap carries darker elements that visually spill over into the barrel before transitioning into the pearlescent white. The custom box is a small plus too: a shared box across the series makes sense logistically, but a pen-specific box just feels more special.

Design Details: Clip, Finial, and Wavy Band

The cap is topped by a metal piece that comes to a rounded point, transitioning into the traditional Narwhal clip. The clip is a bit stiff and takes some finagling with thicker fabrics, though there is nothing inherently wrong with it. One long-standing wish: a clip inspired by the spiraling tusk of a narwhal would be a neat signature element the brand still hasn’t delivered.

The cap angles up before straightening out for roughly the last inch and a half, where it meets the standout design element of this pen: the wavy band. This curved metal ring represents the waves of the ocean, stamped with the company logo on the front with wave imagery encircling the band. It’s unique and it works.

At the end of the cap there’s a medium-size step-down to the barrel, which begins with a generous ink window that the company says represents the sky. From there the barrel declines at an even rate until the piston knob, finished in pearlescent dark brown resin with a rounded end.

Section, Threads, and the Ink Window

The section starts with the cap threads, then transitions through an angled cut into the ink window. Threads at the beginning of a section cut both ways. On the positive side, they act as a physical stop that keeps your grip from sliding off the edge of the section, and the resin here isn’t slippery at all. The downside: the threads on this pen are thin and narrow, so ink works its way into them when you fill the pen and it can be difficult to fully clean out with just a dry tissue. You need something slightly damp to get ink out of the crevices. Other makers solve this with wider, blockier threads that are easier to wipe clean. It’s a minor pet peeve rather than a dealbreaker.

One thing worth highlighting: when the pen is inked, the generous ink window blends in with the rest of the pen, hiding in plain sight rather than reading as a large clear gap. It’s a subtle, thoughtful effect.

Handling, Posting, and the Piston Filler

In the hand, the Horizon Twilight feels comfortable and well-balanced. The cap posts deeply and securely, and posting doesn’t throw off the balance, so if you’re fond of posting your pens, this one will suit you fine.

It’s a piston filler, and the piston operates very smoothly. It’s an honest, functional filling system that suits a pen at this price point well.

The Nib

Under the cap, which twists off with two and a quarter rotations, sits a stainless steel in-house nib made by Narwhal. It’s slightly smaller than a traditional number 6 but a touch larger than a number 5, sitting somewhere in between. It’s available in fine, medium, broad, double broad, and stub.

Writing Performance

The broad nib on this sample is fairly smooth with just a hint of feedback. Don’t expect much line variation. Ink flow is generous, above average, and the feed keeps up well during fast writing. Reverse writing is very smooth and lays down a fine line. Narwhal’s in-house nibs have been consistently impressive, and this one continues that trend.

Paired with a green-leaning ink, the pen is a genuinely pleasant writer, and the generous flow suits the broad point nicely.

Buying Advice

At $168, the Horizon Twilight sits in a reasonable spot for what you get: solid build quality, a custom resin, thoughtful nature-themed design details like the wavy band and the sky-inspired ink window, and a dependable in-house nib. If you prefer a slimmer cigar-shaped pen and like the idea that no two examples look alike, this is worth checking out. If thin threads in the section and a stiff clip sound annoying, weigh that against the design and the filling system before committing.

Conclusion

The Narwhal Horizon Twilight is an interesting new model with features that genuinely work: the wavy band paired with the ink window gives it a unique identity, the custom Starry Night resin is lovely, and the piston mechanism is smooth in daily use. For the price, it earns a spot on the shortlist for anyone after a characterful piston filler.
