New, Unused Ray-Ban Wayfarer Calf Leather Purchased from a store display, so there are some scratches. Please purchase only if you understand this. There is a model called the "Leather Series" that coats the Wayfarer frame with genuine leather. Although I couldn't confirm an official product specifically named "calf leather," high-quality cowhide (genuine leather) is generally used in this leather series, and it is characterized by the ability to enjoy a unique texture (aging) over time.
