Sounds interesting "Revlon Colorstay One-stroke Defining Eyeliner" but not really a defining product. I bought this from health and glow. While applying it was okay but after some time eyes started burning. The whole day I suffered from the itching and irritation. It ruined my mood in the function. It is also not long lasting kajal, It started spreading and a dark circle formed around my eyes. I have a very bad impression and will never turn back towards Revlon. It’s an utterly flop product. Thank god! nothing went serious in my eyes. Please don’t go by the name and look of the product. Be sure while buying spending for such products will last only with regrets.
