I got the trio for blue eyes because, well, I have blue eyes, and there was a 40% off coupon for PF. I almost never wore gel liners because they tended to transfer to my upper lids during the day, and they also dry out over time, making them hard to use and wasteful.
But these liners are great. The trio has a navy blue, a brown, and a black with faint blue shimmer.
The colors go on smoothly and heavily, instead of streaky. They are also easy to control and shape along the lashline. I can do either a very fine line right in the lashes, or a heavier one for a more dramatic, intensified eye. I barely have to pat my liner brush into the pot, and it picks up enough color. If I pick up too much, I just work it into the back of my hand a little bit. The color also lasts all day and doesn't melt under or above the eyes.
I like that there's three colors in one stack. I can use warm brown or cool blue or black depending on my eyeshadow. And the pots take up little space in my kit.
This product has changed me from someone who never wore gel liner to someone who wears it a few times a week. I never really buy PF products, but this is one that should be given a chance.
