The Stila Smudge Sticks were the top launch and gain popularity rapidly. It can stay for a very longer period of time and also can withstand high levels of humidity as well. Other advantages include its readiness at all times, you do not have to sharpen the liner, it is ready to go so you do not have to carry any extra tool while you are on the move. At first, when I bought this liner I swatched this on my hand and after few minutes I rubbed my hand with lot of pressure but you would not believe that the liner did not fade. I called this product a liquid liner in a stick because it usually last for longer period of time. I will not sit back and relax until and unless I buy a black pencil and would love to try out other colors as well.
