This liner is so good! Very creamy smooth application. Glides perfectly. You get a few seconds to work with it and build it up. Once it settles it doesn’t budge. Compared to the urban decay 24 glide liner, I prefer this one!

I received this in exchange for a product review. It is a decent eyeliner, though it was not as smooth when applied over eyeshadow.

I received this eye liner to try at no cost through PinchMe. I really like the color (Flourish) and I really liked that it applied really smoothly with very little pressure. It blended well in my eye corners. It has some great staging power once it's set, keeping a neat line on my lash line for 9 hours Unfortunately, as soon as I put it on, my nose got runny and my eyes started watering. Once I took some allergy meds, this went away. I think it's a very nice product, but depending on sensitivity may not be the best choice for everyone. I will continue to use this, I will just take some allergy meds ahead of doing my makeup. I have not sharpened it yet and hope it holds up well when it's needed.

I got this as a free product sample from pinch Me. I absolutely love the Abstract color in this eyeliner because it really compliments My green eyes. It goes on smooth, and did not smudge even in the high heat and humidity that e have been having in PA recently.

I received the ILIA thru line waterproof eyeliner free from PINCHme in exchange for my honest opinion. I received the color serif. This eyeliner glides on so smooth no tugging and lasts all day. I love that this eyeliner washes off easily. The color is a beautiful deep brown color almost black looking. The deepest brown color I love it.
