American Optical sunglasses. Purchased from a vintage shop and had the lenses replaced and the sunglasses maintained at SOLAKZADE in Harajuku. They are the same model as the American Optical sunglasses worn by Kunichi Nomura. The size is 48-24, which is about the same size as American-made Wayfarers, and the lenses are not small, so I think they will fit many people's faces. The lenses are non-prescription. There are no noticeable scratches or damage, but the nose pads are original and, although not deteriorated, the appearance has changed slightly from the original. Thank you.
