What I’ve Got – Thick/Thin EyelinerI use Maybelline’s Thick/Thin eyeliner and I really like the flexibility it gives me to try different makeup styles. The tip of the brush is flat, so it can be used to paint thick or thin lines, which makes this brush more versatile than most standard brushes. I also like the formula they use, which is fairly waterproof, so it doesn’t smear or smudge from daily use.
