They do sweat...
These are cute glasses, but don't believe it when they say that they won't sweat. They start to sweat a lot more slowly than regular glasses, but if you leave a glass of iced tea on the counter for awhile, they do start to sweat. So don't leave them on wood furniture without a coaster under them! I got the dark green, the red, the orange, and the light yellow. The colors tend toward the muddy side, so if you want something bright, get the colors that appear to be more neon.
