One 16 oz. copper mug engraved with a map of Boston, MA.
Made from 100% copper, our Boston mug isn't merely copper-lined or plated like most others on the market. Each mug is spun by hand of solid copper, the handles are formed and attached, and finally we etch them with our iconic City Maps designs. These copper mugs are a true classic and now we've taken them to the next level. Due to copper's high thermal conductivity, these are perfect for keeping iced beverages cold for long periods (a lazy afternoon, say), especially iced cocktails like the classic Moscow Mule - a delicious blend of vodka, ginger beer and lime juice.
