Im using this product since years and years and is one of my favourite thing on my makeup kit . Its really handy and comfortable to carry it on anywhere . One can use whenever and wherever they like . I would strongly recommend these type of products to teenagers and women . Its amazingly easy to use, just one stroke can make your day and the plus point, its smudge free , water proof and absolute black. What else girls want? It gives a new look on the face . Its as easy as taking pictures , you just have to apply with smooth rounded tip and you can get what you want without any irritation . You can apply it in your own designs and it will look amazing in any way . And even its long lasting .
