Hermès Himalayan 25cm Birkin. The rarest, most desirable and stunning handbag in the world. This bag features a subtle coloration, done in Niloticus crocodile, that is meant to evoke images of the majestic Himalayan mountains. This dyeing process takes many painstaking hours to complete, as the lighter the hue, the more difficult the process. That coloration is paired perfectly with palladium hardware. The preferred Investment Bag.
