Our Minerva Box (Italian cowhide) is a vegetable-tanned leather from Badalassi Carlo in Tuscany, Italy. Minerva box has a pebbled-grain texture that is incredibly soft and supple. As a vegetable-tanned leather, it will darken and develop a rich patina with wear. This is one our personal favourite leathers. Please note that as the pebbled-grain is natural and not embossed, it varies slightly between straps.
