SkoneCosmetics Insanely Intense Tattooed Eyeliner Pen - 5-piece Set - Waterproof Liquid Eyeliner, Sweat Proof, Smudge Proof Liquid Eyeliner - 5 Bold Colors (Black, Brown, Navy, Plum, Hunter Green)

I concur with the other reviewers. This is the best eyeliner I've ever purchased, which is saying a lot since I've been applying makeup for almost 50 years! Because I'm old school, I prefer to apply eyeliner with a brush, but this felt tip is easier than most to apply, and the formula allows just enough time to blend or smudge (if that's your preference) before it completely dries. I have never slept without first removing my makeup, but I wanted to test the "longevity" claims. The result after my very non-scientific study: even after TWO nights, the eyeliner appeared freshly applied. I'm not even tempted to purchase any other eyeliner since discovering this product. My only regret is that it isn't offered in every color of the rainbow ... although, truthfully, the five colors in the collection cover all uses I can imagine. Looking for an all-day and night eyeliner that won't budge even in the rain or shower? Look no further. You just found it! I would be very surprised to learn someone was disappointed and returned this product.

I really wanted to like this product. I was looking for a stay-put eyeliner and was hoping this was the one. Unfortunately, it barely stayed on for a few hours at a time. And it definitely is not waterproof… Even contact rewetting drops washed this away. I guess I will stick with my Clinique Quickliner. So far that’s the best thing I have come across.

This is my all-time favorite eyeliner. It stays on all day and doesn’t smudge or come off in the rain or sweat. Plus I love that it’s like a pen. Super easy to apply and either a really thin layer or to draw a really thick eye.

One of the best eye liners I’ve had. So good I NEED to buy them in bulk! Stays on all day until I decide to take them off.

My wife uses this eyeliner and it holds all day long.
