This is for a set of 2 peace sign necklace connectors.  Some of the holes need to be opened up more for your craft wire to go through them.  The person I bought these from told me they were sterling but they are not marked.  I tested them with a magnet and they are not pot metal, been in my inventory for about 30 years and  have some black tarnish.  Nice pair for your next necklace project.  Thanks for looking.
