In the professional sourcing market, AAA Grade refers to high-quality mirrors of original designs, characterized by superior craftsmanship, high-grade materials, and precise detailing. Unlike lower grades, AAA products must feature genuine leather (often top-grain or calfskin), high-density hardware with anti-oxidation coating, and symmetrical stitching (typically 7-9 stitches per inch). Buyers should look for accurate logo placement and authentic-feeling interior linings such as microfiber or high-quality silk.
