This is a cap from HERMES (Hermès). While it's highly likely to be an authentic item, we cannot guarantee its authenticity because the original receipt and accessories (box, warranty, etc.) are not available. In my subjective opinion, based on the construction and texture, it appears to be authentic. However, please make your own final judgment regarding authenticity. As it is a used item: - There is some wear and tear from normal use. - There are no noticeable major stains or damage. Please check the condition in the photos. If you have any questions, please comment before purchasing. *To prevent product substitution, returns and refunds based on authenticity concerns will not be accepted. Please purchase only if you understand and agree to these terms.
