This liner is waterproof, black and has a felt tip. Im not a fan of the tip because its fairly big and it is quite hard to line the inner corner of my eyes (asian eyes) ; but its fairly easy to manoeuvre around, just need loads of practice and patience.
The ink is not dark enough and I need to layer it for it to really be dark. I do agree that this formula is waterproof as it lasts the whole day on my oily eyelids. However, it does tend to flake a little. I guess the flaking happens because I apply a few layers of it. It is easy to remove at the end of the day and you wont be rubbing your eyelids trying to get every bit off.
Overall, I wouldnt really recommend this eyeliner as there are much better liners out there like the Eyeko eye do eyeliner (review here). But for the price (RM 25), its really not too bad if you just want to try out liquid liners.
thanks for reading!
