This is a very expensive and popular leather, considered the highest grade among various leathers and is also known as the "diamond of leather." The sizes are approximately 1 decimeter on the left and approximately 1.3 decimeters on the right. Please note that these measurements are approximate, as they were taken by an amateur. The thickness is approximately 1.5 millimeters. I believe this is a great deal. Thank you. #leather #leather #cordovan #leathercraft
