The Catrice Black Jack with Black gel liner is a GREAT dupe for Bobbi Brown gel liner! Its truly a fantastic gel liner at a fraction of the cost! For R50, you get 4 grams of product which would last anyone a really, really long time. Does not transfer or smudge once set. Blackest of blacks. To mattify the gel liner, you simply need to press some black eyeshadow onto your drawn line and viola! Instant 40's glamour! Important note: Store all gel liners upside down (lid at the bottom) to prevent the product from drying out. Amazing value!
