This eyeliner pen i received complimentary from OneSizeBeauty is seriously amazing! The pigment, the formula, the longevity—unmatched! I just recently did a few bridesmaids makeup and each one of them I used this product, everyone of them went a full 10+ hour day and went swimming in the evening and the eyeliner still held up great. It’s not super hard to remove but is truly waterproof for those extra sweaty or even swim days. My new go to!

Really loved this and didn't smudge

This is a lovely long eyeliner pen that's easy to get a nice thin line. I love the blue color I got because it's a little different from black and makes my makeup look a little more fun. I did not think this eyeliner stayed on super well, as my eyes watered a bit from coughing and I had to fix the wing right after. It's got great impact but if you're looking for something to stay put, this may not be it. Gifted by One Size.
