I own the black and nude one and they are amazing!
It does everything it says it will do, it's creamy, budge-proof, amazing colour payoff and it's incredible affordable for the quality.
It's also really good for people with oily lids. It won't transfer on your crease.
I purchased the nude one because I have an issue with looking tired all the time and I saw on YouTube that if you put a white or flesh coloured eyeliner in the waterline, your eyes will look more awake. It looks amazing on everyone else but definitely not on me. I looked weird with the nude colour in my waterline. But that's not to say the product was bad, just that the colour didn't personally work for me.
Despite that though, I use the nude liner as a base for my eyeshadows instead. It helps my eyeshadow last longer on my lid, it makes the colour more vibrant and it prevents creasing.
It's a great product and I will definitely repurchase it again.
I personally didn't like these as I felt the colour wore of quite quickly. May just be because I get quite oily skin. Color range was ok though. And very cheap
