        "No Coach model is a close match: the patchwork hobo shape, exterior zip pocket, decorative side panels, and textile lining do not correspond to the listed vintage Coach classic silhouettes.",

        "Condition appears Good to Very Good: visible creasing and handling wrinkles, but no major tears or broken hardware are apparent; odor and hidden interior damage are unknown."
