I got the Fluidity pen in Privet, the dark green. It's a really nice color, deep green with a hint of teal to it. I feel like it's a little dry. I don't have any big problem putting it on, but i do have to go over it a few times on my lid to get solid color. I managed to wing up with no trouble.
The biggest problem is the skin around my eyes is very dry so i use an eye moisturizer. That means the eye liner will eventually smear. It's not the liner's fault. I'll keep experimenting, because i like the convenience of an eye liner pen for my purse and i love the color of Privet.
