Coming from farms located in the south of Brazil (Rio Grande do Sul), it undergoes an innovative tanning process where no chrome, heavy metals or dangerous acids are involved. By simplifying the tanning process, the use of chemicals and energy is limited, the use of water is reduced by about 40% and the use of salt by 80%. After tanning, the water is recyclable. *ethylene vinyl acetate Worn only a few times— LIKE NEW!!!
