These eye colour contour pens are much slimmer than the chubby shadow sticks I normally use, but having said that I do appreciate having more control over where the colour goes as I can more easily do my inner corners and give my shadow more of an angled look at the outer corners.

The actual formula is incredibly smooth (thank you dimethicone!), like skating on fresh ice, and does in fact last a solid work day even without primer. The formula was also surprisingly blendable and not "sticky" like some waterproof shadows can be. I like sticky for doing a single shadowed-look, but for wanting to create some depth having the ability to work the shades like a powder is a plus. I completely recommend these to anyone looking for a fast, quick neutral eyes!
