This is the first time I've encountered such product: A lip tint in marker form. I'm familiar with lip tints, esp. benetint, but not in this form. Frankly, it works for me. Application is super easy, it just takes two strokes, unlike the usual lip brushes that take forever to apply evenly.
It's water proof and doesn't budge unless removed intentionally. Just be careful in layering, you might end up with a bright pink tint which is a tad far from natural. The color suits my acidic skin well.
