These are a good concept but they don't work well. That could be due to the heat, though. The tips of the markers are very thick, making any kind of detailing, even as simple as thin lines, difficult to achieve and messy looking. The amount of "paint" that gets applied looks very thin, so you need to go over lines multiple times to get a good coverage. Even after being left to dry for 20 minutes, the paint smudged really really badly. So it's not quick drying, even on dry skin.
Overall, might be good for very young kids, but anyone who wants a slightly better design is going to be disappointed.
