Copper Coaster Set of 4
IMPORTANT!!! These coasters are all hand made originals and no two are alike!! This set features one each of our four copper coasters - the Mackinac Bridge, the UP, the entire state of Michigan, and the Great Lakes.
Acid oxidized on heavy gauge copper using a 10 day 42 step process. The copper sits on 3/8" slate and is sealed with multiple layers of commercial grade bar top epoxy. This stops any further oxidation and protects your artwork for future generations. Rubber feet protect your surfaces from abrasions. These weigh almost a pound each!
