What it claims:
"Compact, easy to hold high precision liquid eyeliner pen has a smudgeproof, fast-drying formula that glides on to create fine or bold lines without fuss, for looks that last all day."
Hmm...
Easy to hold: Check!
Compact: Check Check!
Fast drying? Uhm.. That was my issue. The liner dried up pretty fast even when it wasn't being used so I couldn't get decent use out of it.
It worked fine the first few times but:
1. I had to keep going over it a few times to get it to actually show up. It's not great if you want a dramatic black line.
2. Due to me having to go over with it so many times, my line looked kind of uneven.
3. It wasn't smudgeproof.
Let's just say I'm on the lookout for a new liner because this ones in the trash.
