Lip Stain Addict I'm actually wearing this product right now. As a person who hates having to constantly apply color to my lips multiple times a day, I can say that this product has been my holy grail. I have one of each color. They have a thin tip but the marker itself is pretty thick. I've noticed that I have tended to use the thin tips of the darker colors for lip liner and the slightly lighter (but not too light) colors to fill in the rest of my lip. The darker colors make it perfect to over line my lips and make them look fuller. Of course, it is just a stain. It stays all day long but it does begin to appear and feel a bit dry on the surface. This can easily be solved with a thin layer of lip balm or chapstick but if you are not into the smooth finish of lip balm then I would not recommend this product. But for the other 99% of us that do wear lip balms, this product works wonders. This brand of lip stain has really become all I'm about especially because of its affordability. It is so inexpensive but somehow feels like a million dollar, high-end product. This has me hooked. Its inexpensive and I'm more than happy to take advantage of this bargain. As a college student, I have to budget how much money I spend on makeup so this has me looking good in the mirror and feeling good when I check my bank account. Definitely gonna take these to the grave.
