I have used the kajal before, which its stay on for the 10-12 hours, no smudging, there is no irritation, no dryness and its not heavy to.Its very smooth to apply and once applies its last for a long time.This is one of the best kajal .but be sure that it is original or not.
Because the one which I bought at first is duplicate where every time I sharpen it, the lead used to broke and its very hard to apply.where the original one is very smooth and easy one.so find the difference if u buy it.
