Circle of Willis Lapel Pin

The Circle of Willis is an arterial ring at the base of the brain that connects the major arteries supplying blood to the brain. It helps to prevent a stroke as it acts as a backup system, allowing blood flow to continue if one of the main arteries is blocked.  Our Circle of Willis pin is hand cast in solid, lead-free pewter.  All of our medical pins arrive packaged on a signature presentation card, making them ready for gift-giving!
