I'm not a huge fan of pencil eyeliners to begin with so I really want to like this product. Unfortunately my eye shape doesn't allow me to wear pencil eyeliner because it gets on my eyelid and my eyeballs sweat so much that it comes right off.
I wouldn't say it's "waterproof" although when I put it on my arm it was more resistant than when I applied it to my eyes. My eyelids sweat it right off even after applying primer potion.
I love the color, but once again I'd love it more if it was liquid. It's like really deep mocha color.
Wouldn't personally buy it but I would definitely recommend it to anyone who does use pencil.
