I think everyone else who has posted here has stated rather accurately just how incredible this particular lipstick is.
Like others have said, it's a matte lipstick that applies like a dream. There's no tugging, or pulling as the formula effortlessly glides over the lips, giving a smooth - and even - finish. And as others have mentioned, the shape of the bullet allows for ease of application. Granted, I do like putting on a little bit of lip liner to give a bit of shape - and a crisp line - to my lips, but I find that can be accomplished with this lipstick alone sans the liner.
It does have a tendency to bleed and a little bit and feather, but not the extent of the other lipsticks that I've used in the past. Otherwise, the longevity is impressive, as it stays put throughout the day. But like any other regular matte lipstick, it will come off when eating and drinking.
The casing is slim, which makes it perfect for traveling.
As far as the shade goes, I love this color. It's a great way to wear a bold lip if you're not comfortable with the more out-there shades that have become popular in recent years. I think the fact that it leans a little bit towards the red end of the spectrum makes it wearable for a majority of skin tones, and I love seeing the varying results. One someone fair, it'll definitely lean true-to-color which is a rich, reddish pink. On darker skin tones, it tends to lean a bit bluer and takes on a more candy-like appearance which is incredibly delectable.
Either way, I think this could easily become a staple in anyone's makeup bag.
