Here are some before and after shots of our copper. We do not treat our copper in any way because many people like for it to tarnish on its own. When you first receive your copper pendant, it will be shiny like a new penny. However, over time, it will tarnish to a nice antiqued look. You can keep your copper shiny by brushing it with fine steel wool. We don't recommend a liquid tarnish remover such as Brasso because it can remove the oxidation in the lettering. You can also let it tarnish like a penny and create a timeless patina.
