Hermès Birkins are famous for being hard to get, generally offered exclusively to loyal customers, but even rarer is the opportunity to special order a custom Birkin. Each season Hermès adjusts the specifications allowed for Horseshoe stamp or HSS bags, and there is the possibility that any HSS bag could be a unique combination produced only once. A rare bi-color HSS Birkin 30cm, an option which has for the past few years been absent at Hermès. This potentially unique bag is a fine example of the fabulous possibilities HSS Birkins hold.
