Round with flat faces, just under 1” diameter. Used with a separate pin, no longer with it. Worn in numbers on the surface of the jerkin, to provide a measure of protection against sword cuts and, in fact, were a form of armor. See current Public Television programming for documentation of these in action. As protectors, they also held spiritual significance for the warrior. Professionally refurbished with the silver overlay restored, on a black leather 18” neck cord for contemporary wear. Jewelry gift boxed with a certificate of authenticity.
