They're from Peru. They're ceramic. They're handpainted. The hole is shoulder to shoulder. Approximately 1.25 inches tall. Just big enough to bull ride the PCB Steer Bead. Some of the PCB holes will take a 2mm cord, some just close to a 2mm cord. Sold in units of 5 so to buy 10 choose 2 units, to buy 100 choose 20 units. The supplier to The Universe for this item, JP Imported, has called it quits so as of 9/17/20 I may be selling the last of what is available to me.
