Donut shaped 3mm by 5mm spacer beads, with a detailed gear wheel shape.
These are nicely detailed cast metal beads, made out of a zinc based metal alloy, which is sometimes sold as "lead-free pewter" or "Tibetan Silver". (The term Tibetan Silver is used freely to describe silver toned beads made out of this zinc alloy, but these type of beads do not come from Tibet, and they do not contain any precious silver metal.)
Please note: These beads are sold by the manufacturers as lead-free, but I have no way of testing that claim. I do NOT recommend using metal beads in jewelry for children, or for anyone who might put jewelry in their mouths. (Small beads present a choking and swallowing hazard, and trace amounts of heavy metals that are perfectly harmless for adults can be dangerous for children, so let's play it safe!)
Also note: The photos may show sample jewelry, demonstrating how the beads look in use. However, this order is only for the metal beads described above. You will NOT receive any finished jewelry with this order.
