This is a pair of glasses that I fancy on Taobao. I want to find a professional to help me see if it is worth it. The customer service said it was Porsche's, and it was Hong Kong Longxiang International Glasses Hall. These glasses are not produced by their company, but authorized by other companies, so don't think so highly of them and the car. I don't know if they are good or bad if they don't cut prices or cut materials. Visually, they are made of pure titanium, and the titanium frame is light and comfortable. I suggest you go to Keji.com and Keke.com, both of which specialize in selling glasses.
