After reaching the heights of popular fame thanks to Grace Kelly’s famous adoration of the bag in the mid-century, demand for the Hermès Kelly bag has remained consistently high. Each bag, hand-made by a single artisan in a process taking over 18 hours, is closely guarded by Hermès and is notoriously difficult to purchase. Despite the Kelly's retail price of over $10,000, gaining access to purchase the bag requires building a relationship with the Hermès brand, typically by acquiring as much as $50,000 in other Hermès merchandise in a multi-year process. On the resale market, Kelly bags maintain a strong valuation over the years, with most bags selling for well over twice their retail value.
