I have to say this is a very decent black eyeliner. It's a blue toned black that has lovely pigmentation. Its definitely blackest black. Besides that, I love the way this glides on to my waterline in just one swipe! I love this for creating a smoky eye as well because its works great on your lid. It's very soft and not harsh at all. The odd thing about it is that it stays on my waterline for maximum 4 hours but on my lid for longer. It could be because my eyes are quite watery all the time! Run to your local Boots now and see if they're still there!
