The Pilot Custom Urushi – Prussian Blue is one of those pens that feels more like a piece of craftsmanship than just a writing tool. The body is made from ebonite and coated in multiple layers of traditional urushi lacquer, carefully polished using the Roiro technique to create that deep, almost glowing blue finish. This particular shade—known as kon-jo in Japan—isn’t easy to achieve, which is why it has that rich, slightly shifting tone depending on the light.
In hand, it’s a large and substantial pen, but it’s surprisingly comfortable because of how well it’s balanced. The standout feature is the oversized #30 two-tone 18k gold nib, which gives a very smooth, slightly cushioned writing feel that a lot of people describe as one of the best in the fountain pen world. It uses Pilot’s cartridge/converter system (with a CON-70 included), so it’s practical despite being such a high-end piece.
Among enthusiasts, this is often considered a “grail pen.” One user put it simply: “This pen is on another level… insanely smooth.” Overall, it’s not just about writing—it’s about the experience. The size, the finish, and the nib all come together to make it feel special every time you pick it up, especially if you appreciate traditional Japanese craftsmanship combined with modern performance.
