(Organic Traced) comes from 100 % organic certified farms in Uruguay, a country known for its farming culture and the quality of its leather. It is the most flexible and finer of our leathers from cattle. This type of leather undergoes a mechanical threshing process that makes it fine and flexible. Tanned in Brazil, it uses fewer dyes than our conventional cattle leather. VEJA uses conventional dyes in accordance with regulations. Particular attention is paid to water during the tanning process. *Vinyl acetate ethylene
