        "The fully fabric-lined interior and modern tote construction do not provide a coherent match to a documented vintage Coach line."

        "Condition appears Very Good based on the mostly clean exterior, with visible creasing and light handling marks; interior condition is shown but odor and hidden wear are unknown."
