Great felt tip. The tip is very sharp and thin. You can make very thin and precise lines. The pencil/pen like design also adds to the ease of use. However, with my hooded eyelids, I found that the line that I drew along my inner corners fade away. But strangely, it does not look smudged. It just disappears. Perhaps it goes into my eye duct? I'm not sure why. I think it could also have to do with my oily eyelids? When I use it without eye lid primer (and with Too Face Shadow Insurance), it still does the same thing. When I rub it, it does transfer on my fingers. If I don't touch it, it stays there except for my inner corners. My guess is that it is the formula and my hooded and oily eyelids. For the price and pen/felt tip design, it is worth a try. But if you have hooded and oily eyelids, I think the formula is not good enough.
