Delta Reservoir Fountain Pen - Wisteria Walk (Limited Edition)
Following the success of the original Reservoir model — a fountain pen engineered with an enlarged ink chamber for extended, uninterrupted writing — we introduce a new expression of the concept: the Limited Edition Delta Reservoir – Wisteria Walk.
What truly defines this edition is its material. The Wisteria Walk resin is crafted by Jonathon Brooks, renowned for his richly layered, hand-poured materials made in the USA. Swirls of deep violet, fresh green, and luminous undertones move organically through the pen, evoking the feeling of a blooming wisteria path in motion. Each piece carries subtle variations, making every pen uniquely expressive.
Accented with warm gold trim and refined detailing, the pen achieves a balance between bold color and timeless elegance. At its core remains the exclusive Ink Tank filling system, designed to deliver exceptional ink capacity and a consistently smooth writing experience. This defining feature continues to set the Reservoir apart, offering true autonomy for those who write without limits.
This edition advances the design with a key innovation: the internal tank, now precision-crafted from high-quality translucent resin. Lighter than the original metal construction, it enhances balance and comfort while maintaining durability and performance.
The translucent Ink Tank subtly echoes the tones of the exterior, adding depth and visual harmony while showcasing the technical beauty within. The result is a fountain pen that feels lighter, writes longer, and stands out effortlessly — a perfect balance of engineering and artistry. Each pen comes equipped with a #6 JoWo steel nib.
The pen is handmade in Naples, Italy and only 88 were made. Each pen is also numbered above the decorate gold band at the top of the cap, opposite of the clip. A bottle of Delta ink and a spare ink tank is included in the box.
We do our best to photograph the pens to show how they will appear in person, but due to the nature of the material, there will be some variation in the pattern seen here. This adds an element of uniqueness to the pen, with no two patterns being exactly the same. We cannot honor special requests.
