Black sunglasses with color adjustment function, lens size 52mm. - Color: Black - Function: Color adjustable (level 1-9) - Lens size: 52mm - Model name: MAX Vario 2-400 - Comes with a case - Purchase price: Approximately ¥9000 Thank you for viewing. I purchased these from an Instagram ad, so I'm not sure if they are the exact same product, but Mercari's AI has identified them as such. I've only tried them on for a few minutes, once or twice, but they don't fit my face, so I'm selling them. Color adjustment can be done seamlessly, but the original memory position was not accurate. There is almost no sign of use or scratches, but I would appreciate it if you could understand that these are used items before purchasing.
