Copper Plated in house by our resident Electrical Artist. We utilize pure copper in a flash copper plating process. They are plated not with just a strike plate, but a full finish plate. Then they are antiqued in a special solution, allowed to dry and hand buffed for a perfect look. Sealed with enamel and then ready to be shipped to you! A special Sarah's Treats & Treasures product, something you can't find anywhere else! George Harris Pins with The Nerd Squad's Electroplating techniques combine to something rather wonderful!
