This type of leather undergoes a mechanical beating process that makes it fine and bendable. Tanned in Brazil, it uses less dyes than our conventional leather. VEJA sources O.T. leather from the Uruguayan Pampa, a region renowned for the quality of its leather and livestock farming. *Ethylene vinyl acetate
