Sailor Pen Patina Ballpoint Review: A One-of-a-Kind Metal Barrel Pen

Introduction

Some pens are bought to be used casually. The Sailor Pen Patina ballpoint is not one of them. Priced at 38,500 yen including tax, it sits firmly in the luxury category, and everything about it, from the presentation box to the finish on the barrel, is built to feel like something special.

What makes this pen genuinely interesting is its barrel. The coloring is applied by Momentum Factory Orii, a traditional craft company, using techniques that produce one-of-a-kind results on every unit. If you have ever wanted a writing instrument that doubles as a piece of Japanese metalwork, this is squarely in that territory.

First Impressions and Unboxing

The Patina arrives in a large white outer box, and inside that sits a black paper box with a matte texture that immediately feels premium. The lid is magnetic, the logo on the front is a simple cutout design, and the back is completely clean. Lift the bottom tray and you find product information, an instruction manual, and a cleaning cloth.

Even before you pick up the pen, the packaging signals that this is not an everyday purchase. That said, the price is high enough that it does not feel like something you can buy on impulse, and it is worth going in with clear expectations about what you are paying for: the barrel, the craft, and the uniqueness.

The Barrel: Japanese Metal Coloring

This is the reason the pen exists. The barrel is brass, finished using a metal coloring technique developed by the representative director of Momentum Factory Orii. The approach is inspired by a traditional technique called “nuka-yaki,” where rice bran paste is applied and burned with a torch to create patterns from the char. The artisans further control chemicals and flames to artificially induce corrosion and rust, producing vivid colors through these reactions.

No two pieces have the exact same color, which means the pen you buy is genuinely one of a kind. The coloring is applied luxuriously over the entire surface rather than just one part of the pen, and it changes over time, so the barrel evolves as you use it.

The color on this particular model is a warm brown-red tone; on Sailor’s official site it is listed as “Brown Patina,” and it reads as a rich, fiery finish on the yellowish brass base. It is worth noting how the same coloring technique shifts depending on the material it is applied to, which is part of what makes these finishes fascinating. Practical detail: despite being metal with a reactive finish, the barrel has no metallic smell and does not leave any odor on your fingers. The surface feels very smooth to the touch.

Weight, Design, and Build

The first thing you notice when picking it up is the weight. At 47.2 g, it easily outclasses most pens, including previously heavy favorites that come in around 44 g. It feels substantial in a way that some people will love and others will not.

Spec-wise, the pen is 135 mm long with an 11 mm barrel diameter, and the center of gravity sits near the middle. The nose cone is brass, slightly curved but mostly straight and a bit long, with a tip length that feels just right. The clip uses Sailor’s signature design with about average tension, and the finial carries an anchor mark that looks cooler in person than expected.

The twist-action mechanism deserves special mention. It operates so smoothly that you might worry it will rotate and retract while writing, like old twist pens, but the refill locks firmly in place and will not retract on its own. It is an impressively solved mechanism. The default refill is the Sailor 18-0500 metal refill with a 0.7 mm ball. Note that it is not compatible with the G2 standard, so a Jetstream refill will not fit.

Writing Performance

On paper, the Patina writes very smoothly. There is slight play in the tip, but it is not enough to be bothersome, and there is no perceptible wobble while writing.

The writing experience itself is excellent. The one caveat is balance: for a pen this long and heavy, a center-balanced weight distribution is not ideal. The pen is hard to balance unless it is bottom-heavy, which means you end up gripping with finger strength to keep it from sliding down toward the tip, and that can make longer writing sessions tiring.

Things to Consider Before Buying

The honest case against this pen comes down to a few design choices. The center ring engraved with the founding markings feels under-designed for a pen at this price; the font selection, size, and the wide empty space below the marking give it a slightly cheap impression rather than complementing the barrel’s finish. A more refined ring design would have better honored the artisan work on the barrel.

The weight is the other consideration. At 47.2 g, this is not a pen for long stretches of writing, and the center-of-gravity issue compounds the fatigue. If you mostly write in short sessions or mostly want a signature, gift-worthy piece, this matters far less.

Buying Advice

The Patina makes the most sense as a luxurious owner’s piece rather than a daily workhorse. You are paying for the beauty of the barrel, the smooth writing feel, the special experience of owning a one-of-a-kind item, and the pleasure of watching the metal age over time.

It is a great gift option for someone who loves stationery or Japanese craftsmanship. It is less suitable for students or anyone looking for an easy everyday purchase, both because of the price and because of the fatigue factor in long writing sessions. If you do buy it, go in knowing that the hardware design is deliberately simple so the barrel can take center stage.

Conclusion

The Sailor Pen Patina ballpoint delivers on its core promise: a simply stunning barrel, real artisan craft, and an extremely smooth writing experience, all in a package that feels appropriately premium. The center ring design and the tiring balance for long writing sessions are legitimate criticisms, but neither changes what this pen fundamentally is: a luxurious, one-of-a-kind piece where you can fully appreciate Japanese craftsmanship.
