I use that kajal from last year and it is very good kajal for eyes . no side effects of this kajal. I recommend to this kajal for attractive and beautiful kajal . If you want beautiful eyes apply it daily. It is 10 to12 hour long lasting life .It is smudge proof and also water proof. You can apply this in summer also without any sweating tension. Lakme eyeconic kajal gives you good look .It is very easy to apply and gives you complete eye make .Yes it is too costly than any other brand kajal but it worth it.its very good brand.for safe eyes.
