I am using 7 Heaven Waterproof Gel Kajal from a couple of weeks and I personally feel that it is totally smudge free kajal .It gives me tremendous result. I recommended this kajal to my friends also and they all were too happy with this amazing product.It makes eyes look stunning, sharp and beautiful. It can also be used as eyeliner and it is not that much expensive that you can not afford. I must recommend all of you guys.I GIVE IT 5 OUT OF 5.HIGHLY SATISFIED.
