I’ve been using this kajal since last 2 years and found it very soothing and cool to my eyes. With other cosmetic kajals I used to get allergy so thought of trying this kajal. Even if I leave it overnight without wiping it out, it does not irritate my eyes at all. In fact eyes feel cool. With a little practise you can get results like other kajal pencils as far as looks are concerned, but yes getting perfect thin lines with this is a difficult task. My eyes look beautiful and feel good since I’m using this kajal.
