This is a high-quality and very popular leather, considered the finest among various leathers and also known as the "diamond of leather." It is expensive. The sizes are approximately 1.2 for the left piece and approximately 1 decimeter for the right piece. 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
