Lightweight carbon fiber frame sunglasses with polarized lenses for clear vision. - Color: Black - Lens Color: Black - Style: Sports Sunglasses - Frame Material: Carbon Fiber - Design Features: Lightweight Design Thank you for viewing. I purchased these new about 4 years ago on sale for around ¥45,000 (original price was about ¥60,000). I only used them once after purchasing and have been storing them since. There are no scratches on the lenses or the frame. They are quite light. The lenses are not too dark and are polarized, providing excellent vision. The case has some scratches, but the sunglasses themselves and the inner bag are clean. ⚠️ Please refrain from purchasing if you are overly sensitive to used items. Please refrain from excessive price negotiations.
