Each stitch was sewn carefully, but as this is a handmade item, please check the images before purchasing. Please note that there may be color unevenness, distortions, scratches, stains, wrinkles, etc., which are characteristic of leather. If you are sensitive to these imperfections or are looking for a perfect finish, please refrain from purchasing. The main body is made of approximately 1.0mm thick, firm leather. Material: Cowhide Color: Black Size (approx.): 21.2cm x 18.0cm Images 8, 9, and 10 show the pen case with 5 pens (from image 7) inside. Please note that the pens are not included.
