This is a high-quality and very popular leather, considered the finest among various leathers and is also known as the "diamond of leather." It is expensive. The size is approximately 1.5 decimeters on the left and approximately 1.4 decimeters on the right. 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
