I have mixed feelings about the Kyliner kit. It works amazing, lasts long and my favorite, black, is a true black. However the gel liner is sometimes dry and I have a bad time using it. The fact that the eyeliner is persistent has its own pros and cons. Okay, everyone likes to have their eyeliner good for the day, but it dries super fast and this doesn't work for someone who's not an expert and may need to correct their eyeliner a few times to get it right.
My personal favorite. It lasts for a long time and you never face issues or see it fading during a long day. I'm in love with the creamy and soft texture, the color and the many many ways you can use and combine them. Just perfect.
