This eyeliner has really impressed me. First, the colour is amazing; it's veryy black and it applies very nicely. The pen tip is a nice amount of flexibility; it is not too stiff that it'll jab your eye and not too loose. It is really easy to draw a nice cat eye with this eyeliner and I think it's perfect if you really want to make your eyes stand out. I've heard many great things about this eyeliner and I was not dissapointed at all :).  I wore this out for a 12 hour day and it did not budge at all. It's now my favorite eyeliner!
