I've been doing cat eyes for years, and liquid eyeliner is my favorite way of doing it. This product has a great tip, and the formula is great. It's not too runny so its not difficult to control. Like I said the tip applicator is great, and makes it easy to go thick or thin. I wouldn't say this formula lasts after anything. If I cry or accidentally rub my eye, it will smear. But that's user error. Would repurchase.
