text: I would not recommend this product. The mug was discolored (had a brown ring and spots) after one use and was handwashed like the directions stated to do. I bought this set as a birthday gift for my husband after reading all of the reviews carefully. He loves Moscow mules and he loves to entertain, so this was a perfect gift! My husband loved them as soon as he saw them...until he used one mug once. My husband has one Moscow mule mug that he has used and handwashed for years and there has never been an issue with it discoloring. I just thought these with their hammered look would be better. Being that I do not want to poison my husband or guests in the future, we will not be using them again. Unfortunately since I am just past the return date, I can not return them but I definitely would not buy these again! Very disappointed after the good reviews.
