Thank you for viewing. This is a vintage, pre-owned Dun Black Titanium frame eyeglasses, DUN-01. I purchased them approximately 25 years ago and wore them for about a year. After that, I switched to different glasses and stored these in a case in my closet. Despite their age, they have few scratches or stains, and the nose pads are clean and in good condition (this is just my personal opinion). They have prescription lenses in them, so please replace the lenses before use. As they are from 25 years ago, I believe they are rare and valuable now. - Frame Material: Titanium - Frame Color: Black - Lens Type: Prescription (Please replace the lenses before use.) Color: Black系 (Black-based)
