I have been using Lakme eyeconic since over 3 years now. This is best ever in the market compared to similar competitors.It is really dark and isblack. Not just normal black but thick black. It stays smudge proof easily for around 6 hours.
I have tried other similar ones of other brands but none of them turned out to be this black. Beware of duplicate and fake ones. The original eyeconic does keep its word and will not disappoint you. When it comes to eyes, always choose the best.
