Is it vert anis? I love that color.
My big concern would be authenticity. Real bags are surely out there, it's just hard to verify their authenticity. If I bought it, I'd like to have a warranty or statement of guarantee from the consignment store and seller, if only for as long as it took me to get it to an Hermes boutique to have it authenticated. And I'm no expert, but apparently the only way to authenticate it is to send it in for service.
