Valentino was pretty much an underdog in leather goods until 2010 when Rockstud was first introduced. Studs are ubiquitous in fashion, but it's the Rockstud that claimed the throne of glam rock, and has almost defined a millennial zeitgeist by its own. 

The construction and materials used by Valentino handbags haven't really changed for the past 10 years, the same serial number and hardware systems you'd seen on a Valentino Nuage bow bag still apply to the Rockstud collections.
