This review is on my wife’s behalf.I am reviewing this for kajal lovers. Lakme has always been the handy and an affordable product. This Lakme Eyeconic Kajal is deep black, intense and very smooth. It glides on the eye very well, but still in a firm way. I wore this on my oily eyelids also and it stays for long time. The kajal stays for 6 hours only on my eyes. It is water proof and it also did not sting my eye a bit. I loved the Kajal but it does not stays for 10 hours as it claims. It only stays for 6 hours. But on an average its a good product. Anyone can buy this product. It was upto my expectation. This Kajal has a twist-up open which retracts back in place. And I think the dermatologically tested claim is absolutely correct.
