It is describe as an eyeliner that based in waterproof, oil, concentrated color three demands, Extreme color, Gelatinous texture and extremely waterproof. You can check out their website www.nattacosme.com fro more info, but it is written in Chinese language. So if you know how to read Chinese language, good for you! So I have tried this eyeliner during my days to the office. First off, I love how this eyeliner is packed. Oh absolutely, it is pink! The downside of this product is that its really hard to differentiate which one is which color as they look the same. The texture of this eyeliner is super smooth.More like a gel texture as you can actually scribble this on the back of your hand and use an angle brush to apply it. It does not goes smoothly on your inner lid maybe because its waterproof. You inner lid is a bit wet right, so its a bit difficult to glide over there. The pigmentation is nice too, not too heavy not too sheer. In terms of waterproof and smudging, well I don't recommend this to be use under your lid as its smudges easily but it stays nicely about 2-3 hours on your lid. It can also be use as an eye shadow, just draw some line on your lid and smudge it with your finger.
Overall, I recommend this to beginners who are exploring pencil liners. Its not too bold and it does looks natural. I love the choco brown color! If you get bored with that usual black liner, go for the brown! It makes your eyes looks natural with a hint of that earth tone natural color.
