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 2 decimeters. Please note that there may be some errors as this is a rough measurement. The thickness is approximately 1.5 millimeters. I think this is a great deal. Thank you. #leather #leather #cordovan #leathercraft #handmade
