I have four colors and LOVE playing around with them.
I don't wear as much makeup as I used to (I'm entering my forties, and with two young kids my life is just busy), and so I absolutely love using the matte fluid eye paints for a quick and easy way to play around with makeup. Everytime I wear one of them (I have 4) I get compliments. Usually I'm doing a simple look, just a quick wing or something like that, but even with simple looks, they make such an impact! 5 stars, 10/10 would recommend.
