NOTE TO REVIEWS BELOW: This eyeliner is not retractable you have to sharpen it with a regular eyeliner sharpener. The plastic is soft so don't worry about it messing up your sharpener.
Now onto the review. I have #13 Poison Red and #14 Mystic Blue. These eyeliners are very smooth pigmented long-wearing and waterproof. They do not tug at my eyes at all during application. I have tested these with the waterproof claim and I must say it's true! I bawled my eyes out while wearing #14 Mystic Blue and it stayed almost entirely intact aside from some tiny insignificant smudges. (Keep in mind that I did not rub my eyes while I was crying. If you do tend to rub your eyes it will obviously wear off and smudge more easily). Nevertheless this is highly impressive. It lasts all day long (which for me is about 12 hours)!
The only negative I can think of is that this eyeliner sets very quickly. Once it sets it is budge-proof. This is fine for people who are good with eyeliner but if you're like me and make lots of mistakes be prepared with a cotton swab and some makeup remover to erase or sharpen up the lines. For my other eyeliners I can usually just use a cotton swab dipped in plain water to erase or sharpen up the lines but not for these eyeliners. Regardless I still highly recommend these!
