Here for your consideration is a lovely pair of glass vintage cuff links. These are rather old and have an unusual back for cufflinks. The post on the back has a lever that pushes in. They only say trade mark on the back. The front is glass . One link has some missing gold inside the horse shoe. The frame looks copper but the back looks more brass. The square part measures 3/4". They have a patina and are left unpolished.Free ship to the lower 48 USA only.
