I will definitely want to try more colors from this CLIO eyeliner range as this is my first item from this brand. I bought the color "17 Black Plum" and it's gorgeous - a really nice purple/plum color with some subtle "barely there" shimmer. Great for green or brown eyes! As for the formula - it's great - very creamy, glides very easily and is definitely smudgeproof and waterproof. You'll need to remove this with a good eye makeup remover, oil or a cleansing oil, because it is indeed longlasting. The pencil also didn't irritate my eyes or cause discomfort, so I feel like it would also be a good option for those with eye sensitivities. I would definitely repurchase and/or try different colors!
