I ordered this eyeliner because I am a sucker for cute eyeliners, and I love Vocaloid! The pen is a little awkward, it's flat and you have to hold it a certain way. But the formula is fantastic. It's a lovely dark color and the actual brush is AMAZINGGGG! Very thin precise tip that allows a great wing, but doesn't bend and ruin the makeup. I would recommend this eyeliner. I think I may purchase the palette and another eyeliner in the future.
