This is a Mitsubishi Pencil uni Walnut mechanical pencil. It's from a house clearance. It's a used item and shows some signs of wear, but there are no noticeable scratches or stains. The mechanical pencil functions without any problems. It's slim, easy to grip, and I think it's a tasteful and chic mechanical pencil. The diameter of the body is about 8mm. Please understand that this is a used item before purchasing. Thank you for looking.
