We've had these for years. The kids found them and like to drink out of them, and they've held up well. (Yes, I know, kids do silly things.) They are lovely and the color is deep and rich.
Got these as a gift for a friend of mine, to match a margarita pitcher I got for her a previous year--these are a perfect addition, well made, and have that right weight feel to them that makes a glass your next favorite to sip out of! Beautiful works of art.
