Levi's 501 black denim, made in the USA. This is a dyed-after type, and the color remains dark, so you can enjoy the aging process from now on. It's a w33, with a waist of 80cm and an inseam of about 70cm. It's a rare model with a Circle R tab. It's a 90s model, and it's very rare because it has a dark color and a Circle R tab. I bought it at a used clothing store in Yoyogi Hachiman.
