The divine proportion
Divina: 618 pieces each
Excelsa: 618 pieces each
The great 13th century mathematician Leonardo Pisano, also known as Fibonacci, discovered an extraordinary mathematical sequence.
The Divina pen
The Divina pen is the result of careful study of the Proporzione Divina and the golden number, phi (1.618), that is present in each part - in the smallest detail and in every part of its awesome structure. The same goes for each of its accessories, from the pen case to the guarantee certificate.
The mechanical precision and reliability of Tibaldi's innovative "perfected" piston filling mechanism, secured by an international patent, guarantees easyness in filling and in writing.
The Tibaldi's striking nib is solid 18K gold, partially rhodium plated.
The cap top is decorated with a pyramid cut mother of pearl or tiger's eye element, embedded into a silver frame.
All the Divina pens are produced as a limited edition of only 618 pcs., a number paying a tribute to the criteria that inspired their creation (phi= 1.618): the magic number of divine proportion
Divina collection includes also a capped roller (convertible in ballpen), that is available in all finishing: black resin with platinum or with rose gold, and ivory resin with rose gold.
The Excelsa pen
The same pen is available also as Excelsa version: its barrel is entirely covered by precious metal, in Clou de Paris decoration.
Excelsa collection includes fountain pen and capped roller (convertible in ballpen) with the same features of Divina.
