I find this is probably one of the best kohl eyeliners I have used, I tend to buy about 3 every time I run out as I feel it works wonders. I put quite a thick line on my inner lids as I have been for about 6 years now. I have tried Revlon, Maybelline, M.A.C..seriously all different brands. But Smudge's kohl eyeliner is definitely my favourite. I do recommend it as it lasts long and creates the perfect smudged look. :)
