I guess it's an okay eyeliner in terms of staying power? It's waterproof and smudgeproof after you allow it to settle in but I don't think it fades a little if you have slightly oily eyelids. The black ink isn't as black as I'd want it to be, the texture isn't smooth enough that the ink can become a little clumpy and uneven on the lids. If you try to layer the eyeliner with some other liners/shadow colour it looks great from afar but upclose it's pretty uneven due to the clumpiness. The pen tip is really imprecise.. it's hard to draw fine, straight lines with it. The good about it is that it comes off easily with oil or even micellar water, and that it doesn't irritate the skin.
