StockPins.com uses many different materials including lead-free pewter, zinc, copper, aluminum, nickel, brass, and others. Due to the custom nature of our work and the wide variety of finishing techniques employed in producing our products we can not economically test each individual product for compliance with prop 65. Therefore we choose to place Prop 65 warnings on all our products when shipping to California.
