Copper craftsmen from Tsubame in Niigata prefecture hand make these mugs using traditional methods that have been passed down for hundreds of years. Copper is 25 times more thermal conductive than steel, keeping your drinks nice and cold for a very long time. The mug itself is pure copper with a food-safe tin lining, featuring a comfortable handle colored by natural processes. 

This mug is perfect for iced drinks like Mules (of course), sours or iced coffee! Do not use for hot beverages!
