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 1.7 decimeters on the left and approximately 1 decimeter on the right. Please note that these measurements are approximate due to amateur measurement. The thickness is approximately 1.5 millimeters. I think this is a great deal. Thank you. #leather #leather #cordovan #leathercraft
