I didn't realize how beautiful lattes could be before I got these glass mugs. I love watching the milk mix while I am making my lattes. Not to mention that the double-wall makes it so that my coffee stays nice and hot for as long as I'm drinking it. These glasses are very durable having been put to abuse tests being accidentally dropped on my granite counter tops a couple of time. I don't remember the last time I used my other mugs because I love these ones so much!
