16 Oz. Solid Copper "Happy Birthday" Moscow Mule Mugs, Set of 4

Everyday is my birthday when I’m drinking ginger beer and vodka!

Misleading, how can it be “solid Copper” then state it has a “nickel finish” hmmm…

The inside is lined because there is some disagreement about copper leaching into the acidic drink. I would assume you would have to drink A LOT of them for it to be an issue but here we are with nickel lining.
