I use the ball-point tip eyeliner - I find it gives me a nice, fine line if I want, but I can easily draw a thicker line with it.
It does seem to clog up with foundation/powder every now and then, so I just kind of wipe it off on the back of my hand to get the dark black back. It is quite wet, and I try to leave curling my eyelashes till last when applying makeup, as it often smudges, particularly when I blink.
Not my fave black pen liner, but a good one that I’ll probably buy again.
The colour is nice but it’s quite hard to use in the fact you have to keep shaking etc it’s a struggle to actually get it out I found. So with that aspect you can’t get it to go on nice and flawlessly, I really struggled with it. Maybe I got a bad one ? It’s expensive for what it is and you can get cheaper ones that are much more effective
