This is a pair of leather strap protectors that will work with just about any camera. These are spares that came with Domke straps. The leather protects the corners of your camera from having the paint rubbed off while being carried by the strap if you're using metal rings to attach strap to cameral. Most camera bodies only have a small metal stud or lug on the corners and require some kind of split ring metal connector (either round or triangular) to attach the strap to the camera. These rub the corners of the camera and often cause paint loss.
