This eyeliner is the best I have tried thus far. It comes in a wide color collection that can be found here
I chose the stubborn brown color to work with my blue green eyes and indeed it is amazing. The eyeliner is waterproof which comes in handy, as I live in Seattle. Alone I gave the product a 4 for its longevity, mainly because I have oily skin and it will eventually start moving around, but if I use eye primer potion with it the product will last the whole day. The color is very saturated and opaque so no layering is needed. It is easy to sharpen the tip so it is very possible to get a clean and thin line with the pencil.
The power point eye pencil is an excellent product and I look forward to buying more colors.
