Ray- Ban vintage small brown sunglasses leather CASE ONLY EMPTY

Vintage Bausch & Lomb Ray-Ban small brown leather sunglasses case with snap closure . Circa 1960s. These were for clip on sunglasses but listed here is the EMPTY CASE/ CASE ONLY- NO GLASSES. Overall very good vintage condition- the outside has some minor wear, scratches / stains/ rough spots etc, see photos. The inside looks near excellent, clean, soft suede, there is something at the bottom, it might be a small hole but it doesn’t pierce through the underside, so I’m not sure what it is. Measurements in the photos.
