I ordered the black and amber brown ones: black for my everyday make-up (at least what I used to do)/chic make-up and brown for more natural looks...and since then I've totally fell in love with the brown one/natural looking make-up. They're really pigmented and creamy so it makes the application easy. It really doesn't smudge either!! So if you want to blur the line a bit like I do you have to do it right after you've drawn it. Because it doesn't smudge easily, it stays for a long while too.
They're my favorite make-up items at the moment, I don't even use liquid eyeliner anymore even though it used to be a must for me.
