The pen features our classic bridge clip with laser engraving of the Visconti logo. The closure of the Homo Sapiens Dark Age is made with the characteristic bayonet system, patented by us. The lava must be produced in pieces with a maximum length of 8 cm. We work each piece, after its shaping and seasoning, on dedicated machine tools with particular characteristics. Before assembly, the parts are polished with particular processes which then determine the final leather/soft effect.
