A mug can be seen everywhere, but this doesn't make it mediocre. On the contrary, there are always some special mugs that can catch your eye, and the mugs we produce are among them. After the famous cocktail "Moscow Mule" was created, this kind of mug is more and more popular. The classic mug was made of copper, however, when acidity involved in the drinking of a Moscow mule, it may cause copper toxicity. So we use 304 stainless steel with copper plating instead, which is 100% safe for human body.
