The lakme eyeconic kajal black is very very good in application. it is very smooth. you can easily apply it either on your lower or upper eyelid. it is smudgeproof and very long lasting. it also works as eyeliner. you can replace your liquid liner with lakme eyeconic kajal. it does not harm your eyes. I am using it since last 3 years and I never felt any problem in my eyes due to this kajal. this is best. I am loving it. I would highly recommend it. thank you.
