Each pair of the popular Persol is a masterpiece on its own, combining functionality, style, quality, and optimum comfort. This is because parts of the production process of Persol eyewear are still handcrafted, including the making of the Arrow that defines Persol, the Persol’s unique Meflecto system, a manufacturing process which involves inserting small cylinders into the acetate arm to give it flexibility, as well as the special process called ‘telatura’ that consists of eliminating edges on the underside of the bridge to make the fit more comfortable.
