Visconti is delighted to announce the latest addition to their Homo Sapiens demonstrator collection - the Demo Stones. Vibrant transparent resins meet the iconic design of the Homo Sapiens collection; a natural encounter with light, adding transparency, depth and fluidity. Three demonstrator colors were selected by Visconti for this collection, each inspired by the beauty of the most sought-after colored gemstones.

This fountain pen is inspired by the red ruby, and is enriched with a semi-precious red carnelian stone in the top of the pen cap.

Each Demo Stone is designed, made and polished in Visconti's Florentine workshop. The barrel and cap are made from turned acrylic resin and carefully hand-polished, both inside and out, with special felt tools, to guarantee an excellent result.

Visconti's ability to make beautiful demonstrator pens is renowned around the world. Crafting the Demo Stones from transparent resin was not purely an aesthetic choice but also a way to reveal the beating heart of the Visconti demonstrator pen: the double reservoir power filling system. Visconti's patented Double Reservoir Power Filler is a unique filling system that allows a greater ink capacity and safe usage during air flights. The vacuum power filler is made of titanium to resist ink corrosion.

The pen caps using the Visconti 'Hook Safe Lock', a revolutionary capping system so you can cap a pen without worrying about the cap accidentally unscrewing in your pocket and leaking. The bridge clip of the Demo Stones pen is engraved with the Visconti logo and embellished with a tone on tone enamel.

The fountain pen is further enhanced with Visconti's large in-house 14kt gold nib, and is set in a gift box.

Each pen may be personalized with Visconti's patented "My Pen System" at the bottom of the pen's barrel.
