Thank you for viewing. This is a pouch made using used denim. The size is approximately 11.5cm in height, 17cm in width, and has no gusset. It has a D-ring attached. The tag is laser-engraved on leather. The medical record book is for size comparison. This is a handmade item using used denim, so there may be some misalignment, distortion, re-sewing, and damage to the fabric. Also, the color may be slightly different due to the digital camera image. Thank you for your understanding.
