This is a high-quality leather, considered one of the finest among various types of leather, and is also known as the "diamond of leather." It's expensive and very popular. The sizes are approximately 1.4 for the left piece and approximately 1 decimeter for the right piece. Please note that these measurements are approximate due to being taken by an amateur. The thickness is approximately 1.5 millimeters. I believe this is a great deal. Thank you. #leather #leather #cordovan #leathercraft #handmade
