We use real copper which means your hands WILL smell like pennies!
However, here are a couple of options to help (these DO void your OG Guarantee):
Apply a Top Coat - Using regular Rustoleum matte (or gloss - your preference) top coat spray, you can give those items a good spray to your liking, and that will lock in that pristine copper look (no patina will occur) and no more penny smell!
Forced Patina/Apply Top Coat - Prefer that more shipwrecked look...then get your gloves and masks and let's do a little science...using ammonia and table salt you can take those copper beauties to a whole new look with a patina of your choosing! Once you have that perfect patina, use the same top coat method discussed above to lock in that look, and those will be preserved with no smell and a cool new look!
