I got mine through an event on beautynetkorea.
The Lip Tint has a watery texture that means that you have to spread it as fast as possible because it dries out quickly. It lasts on me up to 7 hours~ it leaves a stain after you drank or ate something so I recommend to reapply it then.
I recommend to use this liptint as a "topcoat" on your red lipstick. It gives you a brighter color and lasts longer with that method (up to 10 hours for me but you should reapply it after eating or drinking)
