Visconti conceived the Homo Sapiens writing instruments line for real writers, for those to whom the fountain pen continues to represent a travelling mate, a daily friend to share with the same civilization that writing contributed to create. The material in this pen is as antique as the world: lava from the Etna volcano. Nevertheless, it has several characteristics that render it unique in the manufacturing of writing instruments. Visconti has successfully produced a material containing over 50% of pure basaltic lava, catalysed together with resin in a formula – patented thus obviously kept secret -whose extraordinary characteristics practically transforms it into a material perfectly fit to writing instruments. The Chiantishire collection is limited to 888 pieces worldwide. A perfect addition for pen lovers to their collection.
