Hi - I am in the market for a mini rectangular in black caviar leather with gold hardware. I know these are seasonal releases, but I am wondering how often they come out in black caviar (I often see lambskin but not caviar as much)? Also, was there something unique about the black caviar minis in the 21 series (released in 2016)? I saw a post on a consignment website about these being a “special” release but wasn’t sure if that is the case. Thanks!
