Ok, so I am just going to say this with all honesty... this is the liquid eyeliner I've been looking for my whole (winged-eyeliner-wearing) LIFE. My whole life, ok?! I have eyeliner-challenged lids (heavy lids that tend to be oily) and I have tried everything: cheap to spendy, grocery store to high-end, pencil, gel, liquid... non-smudge, stay put, waterproof, never-smear... I have never found a single of these products that does not transfer to my upper lid. None. Ever. Hence, I had given up, thrown in the towel, retired entirely from winged eyeliner. And then... Birchbox sends me this beautiful, slender tube of black gold. I said to myself... well let's just try this on, just for fun. We can pretend we're one of those girls who can wear winged eyeliner, just for a few minutes... until it transfers to my upper lid and looks completely asinine and I curse the stars, yet again. WELL. May I tell you my delight when I realized this was THE eyeliner??? The one?! DELIGHT! Sheer delight. Oh be joyful the day. I have been winging my eyeliner with grace and smudge-freeness ever since. PLUS, it comes off quite easily! I have tried gels that were very hard to remove and this just takes a little gentle cleanser and water. My only wish is that it dries out a bit sooner than what I'd like, but that's ok... I will deal with that. Thank you, Birchbox!
