These sunglasses are from Kaneko Optical, and the lenses have a reddish-brown tint, giving them a unique look. I had the case and a screwdriver for adjustments, but I've lost them, so I'm only selling the sunglasses themselves. I often get compliments on how cool the sunglasses look, but the gold frame and color don't really suit me, so I'm selling them. Please refer to the photos for details. I'll answer any questions you have to the best of my ability. Thank you for looking.
