This is a very expensive and popular leather, considered the highest quality among various leathers and is also known as the "diamond of leather." The sizes are approximately 1.4 decimeters on the left and 1.6 decimeters on the right. Please note that there may be some errors as these measurements are approximate. The thickness is approximately 1.5 millimeters. I think this is a great deal. Thank you. #leather #leather #cordovan #leathercraft #handmade
