Leather from BADALASSI CARLO Badalassi Carlo, a tannery founded by CARLO BADALASSI, who was a professor at a leather school in the Santa Croce region, has been producing leather for more than 40 years by integrating the traditional vegetable leather processing method developed in Tuscany with his unique theory and technology.Vegetable leather processing is an eco-friendly leather manufacturing method that takes a long time to complete by tanning leather only with tannins extracted from plants. [Minerva] BLACK Case Minerva leather, unlike Minerva Box, is a plain, un-milled leather that looks matte at first, but as it gets used, the color deepens and the luster increases, so you can see and feel the change over time.Minerva is a vegetable tanned leather made using the unique Vacchetta method from Tuscany. At first, the leather looks matte with a lack of sheen, but over time it adds a natural luster and deepens the color. This is because there is no artificial coating on the leather surface, so the gloss rises naturally from the oil contained in the leather itself as it is used. As with other vegetable tanned leathers, Minerva is especially beautiful with time.
