Delta Reservoir 2.0 Numbered Fountain Pen Blue/Grey Special Resin 925

Following the success of the first Reservoir model — our fountain pen designed with an enlarged ink chamber to ensure longer and uninterrupted writing sessions — we proudly present Reservoir 2.0: a new step forward in design and functionality. At the heart of the project remains our exclusive Ink Tank filling system, engineered to deliver superior autonomy and an exceptionally smooth writing experience. Today, this system evolves with a substantial innovation: the tank, originally crafted in metal, is now precision turned from high-quality resin, chosen for its lightness and durability. Adding to its uniqueness, the new model features an exclusive blue/grey mother-of-pearl material, a refined, shimmering tone that plays with the light and gives the pen a contemporary and distinctive character. The result is a fountain pen that is lighter, more balanced, and more comfortable, ideal for those who wish to carry a true ink reserve wherever they go. The new resin that has been used to realize the new INK TANK, translucent and in a color that match perfectly with the pen’s color, beyond reducing overall weight, enhances the tactile and visual pleasure of the writing instrument while preserving the technical soul and elegance of the original design. Reservoir 2.0: the same spirit, new lightness, new brilliance.
