Product Design Ⓒ Xezo

This fine-point fountain pen features a cap with hand-inlaid polished panels of genuine black mother of pearl that shine and shift in a spectrum of colors in the light. The round lower barrel is made of solid hand-guilloched, hallmarked 925 sterling silver. The fittings are .999 platinum-plated brass. Each luxury pen is limited edition and serialized.

The natural geometry and iridescence of the black mother of pearl, stripes of wave-like guilloche engravings, and the platinum leaf-patterned band come together with inspiration from Art Nouveau to emulate the artistry of nature itself. Altogether, this makes for a pen that is not only a useful writing instrument but also a unique work of art.
The black mother of pearl we use is a natural material, and every piece is unique. Due to this, some distinctions in the colors and textures in these pens may occur. Colors can range from greys, blues, greens, pinks, and black. These are not defects, but rather natural attributes that help make your pen one of a kind.

Every Xezo pen is backed by a three-year warranty against defects in workmanship and parts.


Please note that our 925 sterling silver is pure and not plated. Silver will naturally tarnish (turn darker) over time, depending on use and storage conditions. We recommend that you polish the silver every 6 months, using the provided polishing cloth or your preferred silver polishing product.

The production of each Xezo pen model is limited to 500 pieces or less (excluding some series, such as the Maestro Sea Shell FPG/B/RPG and the Legionnaire). Each Xezo pen is a handcrafted collectible item and an exceptional gift for a pen collector—one day destined to become a vintage heirloom.

Please note: Our fine size nibs have a tolerance range due to the milling process. Therefore, upon customer request, we can select the equivalent of an extra fine nib (line width of ~0.3mm) from our fine nib stock, although the nib will be marked as “F” and not “EF”.
