Vintage Connector: Green Glass & Faux Pearl on Golden Metal

What versatile pieces these are! These little connectors were made in Japan sometime in the mid-20th century. Each of the beads is 4mm in diameter. The little green beads are glass, while the faux pearl appears to be plastic. They are centered on golden metal with a loop at each end for easy connecting. They measures about 19mm long (around 3/4 inch).
