Description The Homo Sapiens fountain pen in Bronze Age is handmade from hardened basaltic lava sourced from the Mount Etna volcano in Italy, with a trim made of solid bronze, and it features a rose gold-plated oversized 18kt gold nib to match the trim color. Visconti lava is virtually unbreakable, comfortable and warm to the touch - and slightly hygroscopic, absorbing moisture from your hand. The basaltic lava is mixed with resin to create this pen.The fountain pen caps by 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 or pen case, and leaking. The vacuum power filler is made of titanium to resist ink corrosion. The Homo sapiens 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.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.
