Delta Reservoir Ink Tank ST Fountain Pen

The Delta Reservoir Ink Tank System Fountain Pen blends modern engineering with timeless craftsmanship. Central to its design is the advanced “Ink Tank” system—a high-capacity, easy-to-use solution that eliminates the mess and hassle of traditional refilling methods. Each pen comes with a pre-installed 2 ml ink reservoir and an additional spare, offering a combined 4 ml of ink to keep your writing uninterrupted.

Swapping out the reservoir is simple and clean: just replace the used tank with a fresh one—no tools, no ink stains. This seamless system is perfect for professionals, creatives, and everyday users who value efficiency and reliability.

Crafted from premium Italian resin and hand-turned from solid bar stock, the pen offers outstanding quality and a comfortable, mid-sized shape inspired by Delta’s DV line. A 925 sterling silver cap band, meticulously handcrafted, adds an elegant accent to the pen’s design.

Choose from a wide range of stainless steel nib options, including EF, F, M, B, Stub 1.1, Stub 1.5, Flex EF, and Flex F, to suit your unique writing preference. The pen arrives with a pre-loaded Ink Tank, a spare reservoir, and a bottle of Delta ink to get you started right away. A user instruction card is also included for easy guidance on using the Ink Tank system.

Designed for convenience, the 2 ml Ink Tank refills are compact and portable—ideal for travel, long writing sessions, or daily use. They ensure you’ll always have ink when it matters most.

Whether you’re a dedicated writer, a working professional, or a passionate collector, the Delta Reservoir Ink Tank System Fountain Pen offers a reliable, elegant, and efficient writing experience.
