Description 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. The 3 demonstrator colors were selected by Visconti, each inspired by the beauty of the most sought-after colored gemstones; Ruby, sapphire and emerald. Each pen is then enriched by a semi-precious stone in the top of the pen cap: green agate, blue agate, and red carnelian stones, to emulate the three inspirational gem colors of the pen bodies. The Visconti Homo Sapiens Demo Stones fountain pen in Ruby features Visconti's patented Double Reservoir Power Filler, a unique filling system that allows a greater ink capacity and safe usage during air flights. The fountain pen is further enhanced with Visconti's large in house 14kt gold nib, available in EF, F, M, B, and 1.3mm Stub. The bridge clip of the Demo Stones pen is engraved with the Visconti logo and embellished with a tone on tone enamel. 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. The Homo Sapiens Demo Stones fountain pen can also be customized with the magnetized MyPen System, such as natural stones, zodiac signs, or initials that you can swap into the finial in place of the Visconti logo coin at the bottom of the pen barrel. As of April 2023, all 14k and 18k gold Visconti nibs have been inspected and tuned by a nib worker and despite our best efforts to fully clean each pen may exhibit some minor traces of ink in the nib and feed, but have in no way been filled or previously owned or used.
