They're from Peru. They're ceramic. They're handpainted. It's been so long since I've seen one and I've spent more time in the woods than almost anyone you know. Drilled top to bottom. Approximately .75 inches long, .50 inches wide. Commonly thought to have gone extinct at the time of the flood (Noah's not Montpelier's) they actually were hunted to extinction by Sasquatch. And that's why you don't see so many Sasquatches any more. The unicorn was their primary food source. PCB = Peruvian Ceramic Beads. Takes 1mm cord or smaller.
