Vintage copper bangle and post earrings

Copper colored cuff bracelet and post earrings in an elongated pentagon shape. I do not think these are solid copper. There is a spot on the cuff where the finis is scuffed. The bracelet is not magnetic but the earrings do attach to a magnet. The cuff is 1 5’8” wide and 7 1/2” circumference. The earrings are 1 3/4” x 1 3/8”. These pieces have a nice age patina.
