Review (5/5): Works great! Will buy again!
I have tried other waterproof, all-day eyebrow pens before and some were good at first but dried up after 3 or 4 uses. I purposely waited 3 months before reviewing this product and they are still working great. They are definitely smudge-proof and water-proof but come off easily in the shower with soap and water. I wasn't sure which color to get so I bought both the dark grey color and the brown since my eyebrows are black but I have blonde hair. I'm glad I got both - I use the black/grey one to draw small individual "hairs" and then I use the brown to fill it in for a more natural look. I will definitely be purchasing again -
