Shungite protects from EMF. It neutralizes tension and stress. These come from Karelia, Russia. Check the measurements next to a quarter, which is approximately one inch. These measure 30-40mm. The price listed is for one disc.
After USPS Mis-Delivered my order. Kerri filed claim after claim with them until She finally got me a refund! I was so surprised and grateful beyond belief she went above and beyond! Wish I could find and change my review. Kerri Rocks!
