Im using it since last one year and I found this to be really useful and price efficient.
It does not cause any skin damage and last for a long period and also its smudge proof.
Its easy to handle and just one stroke is enough to get a perfect finish.
I advice everyone to use it rather than using any other cheap quallity materials.
Proffesionals or businesswomen who have limited time to dress up should use Maybelline Colossal Kajal.
