Glass has been made in Venice, on the island of Murano, for over a thousand years. These Tinti Matteo glass cufflinks are also made in Murano, Venice. Tinti Matteo is the current owner of the glass factory, whose father Giuseppe's Sonja and Tuomo met in Venice. Giuseppe, who is now over 70 years old, has transferred the company to his son, who still makes glass jewelry and household items using traditional Murano methods in Venice. Gold and silver are mixed into the glass, as well as other substances to bring color. With the help of glass, a wonderful three-dimensional piece of glass jewelry is created, which arouses admiration in the cuff. The metal parts of the membrane buttons are nickel-free and hypoallergenic, so they do not cause allergic symptoms.
