A pair of collapsing binoculars—the glass lenses are mounted in a grey metal frame. The lens brackets are hinged, allowing the device to open parallel to each other so they function as a sort of binocular telescope. The smaller, diverging lenses are able to slide towards and away from the larger, converging lenses. They also accompany a brown leather enveloping case (not pictured) that measures 117 mm. x 74 mm.
