I'm in love with these liners! OMG! They are the most gentle liners EVER yet! This applies so smoothly, all I can do is repeat the word EFFORTLESS. A brightening light/medium beautiful shimmery mint/emerald/teal/aqua polychromatic color that looks STUNNING tight-lining, upper or lower lash lining! In one swipe, I get insane payoff, but in two, I have a color beyond even other higher end pencils I've bought in this color range. Non of these liners are dupable in my opinion. This color gets to an ethereal place I've dream of! Easy to use, genius execution, excellent packaging, perfection found. My eyes are sensitive, and this is soothing both the skin, and my mind! (Money well spent. This will last soo long, totally worth the splurge, would buy every one of these if they came in colors I wanted.) lasts until I take I take it off, Intro(vert) is a mermaid color making this introvert quite satisfied! <3!
