They are made from the first run of plastic in my husband’s injection molding machine. He made a mold for a simple hexagon chip to use for testing new plastics and new techniques. I immediately grabbed a handful of the cooled off runners from the first run and stuck them in my craft stash.
I clipped the hexs off the sprue, drilled holes in them, and stuck some jump rings through - silver plated jump rings and ear wires. The hexagons are raw polypropylene with no colorant. I’ll probably have another pair when he does color runs
I made these earrings mostly to keep a commemorative item that is useful from the first run. Its been a journey for him.
