This is a set of 8 Keyuca pinch hangers. They all look the same, but the 5 hangers on the left in the first photo have hooks that are not fixed (they spin around), while the 3 hangers on the right have fixed hooks. (I believe this is a specification change, as I recall purchasing them additionally.) I checked the Keyuca website, but they do not seem to be selling them, so they are likely discontinued items.
