Stila Stay All Day Waterproof Liquid Eye Liner, Micro Tip, Intense Black, 0.01 Oz

This is my all time favorite eye liner - it lasts forever (both in terms of through the night and the amount of liquid it holds)!! I don't use a lot of make up, but this is super easy to use. I can go from a super thin line or thicken it up and the micro tip works for both. This eye liner will. not. budge. It can be 90 degrees with 90% humidity while you're at a concert for 8 hours, and this will stay put. It's basically a tattoo until you use soap. I've tried other eye liners that were slightly cheaper thinking it wouldn't be a huge difference, but I've never been more wrong. There's a reason this is a cult favorite. Highly recommend!

I love this product, and I have tried numerous brands. This always wins out. Makes a smooth even line. Doesn't smudge, and lasts into the next day.
