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 sizes are approximately 1.1 decimeters on the left and 1.6 decimeters on the right. Please note that these measurements are approximate, and some variation may occur. The thickness is approximately 1.5 millimeters. I believe this is a great deal. Thank you. #leather #leather #cordovan #leathercraft
