This product was a little throw in with a gift I got and it wasn't quite as good as I hoped.
The packaging was sleek and simple. Giving the product a sharp look. The pastic of the packaging was fairly standard as was the colour. Making for practical but not memorable packaging.
The formula inside was a little bit runny. Which I prefer to those that dry up or are too thick. But of course I'd prefer it to be just right.
In terms of longeviety this eyeliner did not last all day which is unfortunate but expected at the price.
In terms of application, being runny it could also be a little messy to apply. But did create nice clean lines if you didn't mess it up.
As for being waterproof, I think it comes off a little too easy to be waterproof.
I personally prefer a more expensive pen styled liquid eyeliner that I don't have to reapply.
I liked the darkness of the black with this eyeliner but I didn't really like the brush. For me it made it quite hard to apply (although I'm not incredible at applying eyeliner so it could just be me haha) I wore it to a party and after an hour or two it started flaking off and looking unfinished and just bad in general. It says that it is smudge proof but for me it didn't seem that way at all because when it flakes (after an hour or two) It tends to travel elsewhere on your face which leaves marks. I wouldn't recommend this to a friend and I would look for a different brand for liquid eyeliner. I have changed to gel eyeliner now and love it but if I wanted to try a liquid one again I would look for something else.
