This is a high-quality leather, considered one of the finest among various leathers and is also known as the "diamond of leather." It's expensive and very popular. The size is approximately 1.1 decimeters on the left and approximately 1 decimeter 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 think this is a great deal. Thank you. #leather #leather #cordovan #leathercraft
