I love eyeliner. LOVE. And I fell head over heels with the Kat Von D Beauty Ultra Ink Liner as soon as I used it. This eyeliner is extremely, extremely black, which is fantastic because most eyeliners are always a touch grey; even when it starts off black, it eventually turns grey. Why? If you can explain this strange phenomenon, please DM me. However, this eyeliner doesn't do that — it draws on black, and stays black. I love the fine tip because it means that you can go in between the little lashes to really make the lash line look bigger, deeper, and fuller. That little flick I do when I want a cat-eye is, yep, so much easier now too. That tick is sharp, guys! It also has a sponge applicator, which means my application is not too wet, glides on like a dream. Totally foolproof. Another bonus is that it's waterproof, and it won't budge even when you want it to. It's one of my new favourites.
