This Buxom eyeliner from Bare Escentuals is such an effortless liner to use. It glides on so easily and you really don't have to put any pressure on it at all. There is really no need to keep having to go back and forth, waiting for the color to come out. It is really great for smudging especially, but sometimes it smudges a little too easily. There is no irritation whatsoever to the eyes. However, the lasting power leaves something to be desired especially on the inner rim of the eyes. On the plus side, they added a built in sharpener which comes in very handy and is just attatched to the bottom, you probably wouldn't even know it was there if it didn't say so on the description. The available colors are in Emerald (evergreen), Onxy (black), Pearl (true white), Sapphire (teal indigo), and Topaz (dark warm brown). I got the liner in Topaz and it is a really great color, a nice dark brown. Although it wouldn't be my top choice, it certainly is an amazingly easy to use eyeliner. I would reccomend using it mostly for nights out, as it won't last through the day but it does do pretty good at night (particularly on the outter rim).
