25mm lucite pendant, made in West Germany, controlled bubble design. Top hanger. Because of the process used to make these, you can't see any mold lines--which is a mark of high quality. What a great necklace pendant, or a big bauble to swing off the side of a statement bracelet. If you're bold, make them into earrings! Sold by the piece, while they last....they are vintage, made in the 60's-70's.
