Hermes handbags also come in exotic materials such as ostrich, lizard, crocodile, and alligator skins, available in glossy or matte finishes. Hermes bags made from exotics are considered more exclusive and unique than leather Birkins and fetch a higher price point. Out of all the exotic materials, ostrich has the most entry-level price point and is the most durable. This material has been used by Hermès since the 1920s. Identifiable by its follicles, the points from which the feathers grow, this skin has a very pronounced dual tone. In order to prevent follicle damage, Hermès flattens the follicles and triples the skin. This material absorbs oils and will darken over time where it is frequently touched. Like lizard, this material is available in an assortment of vivid colorways. Ostrich skin bags do not have a special symbol stamped on the bag.
