I have been using Maybelline Colossal Kajal for almost two years now. The kajal pencil is sleek and easy to use. The kajal lasts for almost 7-8 hours after application. It has a smooth texture and easy to apply on eyes as it glides smoothly. It’s smudge proof and water proof. The product description says that it stays for upto 16 hours. I haven’t tried wearing the kajal for so long but it definitely stays for 7-8 hours. It smudges a little but only after a few hours which is acceptable. Just 1-2 strokes of the kajal gives you good color intensity. It’s very easy to apply on daily basis. This sleek kajal pencil can be easily carried in your purse too. It gives a perfect and beautiful look to the eyes and should be a must-have in your cosmetics collection.
