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 1.9 decimeters. 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 #handmade
