Upon receiving the products, I set to test them as I tend to wear my make-up pretty hard. I play sports on weekends and decided to really push the limits by wearing the black eyeliner (with a primer base to counter my naturally oily skin) out for a few hours of sweating in the sun. After around an hour and a half, I was not disappointed!

I would compare the durability of Brian Eyeliner to NYX waterproof eyeliner, if not just a bit better. It's all-day wear even for someone who lives in a humid climate.

What really sets it apart though is the tips; I find myself reaching for these any time I need to get a thin detail line JUST right. The application tip doesn't bend like other eyeliner products do (which leaves unwanted blotches in your designs). It's basically a fine-tip market pen but made to last on your skin without feeling heavy or like it's clogging your pores. This product really does allow you to unleash your creativity for any occasion.

The one thing I have to say on the slightly negative side is the silver eyeliner (which is not sold on its own, but only comes in the full set where the price is negligible considering all the other products you get at a reduced rate) is extremely transparent and doesn't really do anything. That aside, I'd say this product is well worth it for anyone who likes to really express themselves in unique ways that really stand out!

So pigmented and durable! These do not budge at all! Just came back from a Seventeen concert on a SUPER hot/humid DC day. It couldn't be removed until I used oil cleanser later that night. Thank you for surviving one of the best days of my life!

The pen doesn't dry out, the color payoff is exactly what you see in the ads, and I recommend this pen to everyone I talk makeup with.

Want to get it in more colors the precision tip is great!!

I'm so impressed with this liner, not only was it just as pigmented as it promised, but it's pretty smudge and water resistant! I think I just found my favorite new liner!!
