It is very easy to use. Draw it on, easy peasy, and you are left with a lovely thin, neat line. I am a fan of thin eyeliner which you can draw over to be thicker if needed, so this is a massive plus. Sadly, that is where this eyeliner and I end our friendship. The black is no where near as opaque as I like with my eyeliner, nor is it as glossy. I also found that while this eyeliner was as smudge proof as can be on the dry skin on my hands, it began to smudge after about 4 hours on the oily skin on my eyelids. Not ideal during a working day.
I believe that this would work better for those just getting used to applying liquid eyeliner (before graduating to a gel eyeliner, or a "pot" eyeliner), and for those who have dryer skin on their eyelids. If you fit into either of those catergories, maybe give it a go. Sadly, this eyeliner will not replace my beloved Rimmel Professional Glam Eyes Liquid Eyeliner, but if I am going for a softer look witha less dramatic line, this might be the one that I turn to.
This eyeliner was won as a prize. I am in no way obligated to review this product.
