        "No direct replica concern is established because no purported Coach branding is visible; the primary concern is non-Coach lookalike or unrelated brands."

        "Condition: Good to Very Good overall based on visible creasing, light surface marks, and normal handling wear; interiors, odors, and all corners are not fully assessable."
