Blackberry is a gorgeous color and probably the most pigmented out of all the glazes. But it still only gives a hint of color- a reddish berry color. It's super shiny, too. Those are the good points. The bad points are that the shine and color don't last long at all, even for a gloss. It also bleeds outside of my lip line. And there is a ridiculously small amount, especially considering this is one of the most expensive glosses out there. I did a quick comparison, and my Nars gloss comes with .14oz, MAC is .17 oz, Chanel is .19 oz, Clinique is .25, and Lancome is .5. How much Stila gloss do you get in one pen? .05 oz!!! That is SO ridiculous, considering almost all the other glosses I listed are either cheaper or the same price. And get this, I have a free sample of a Laura Mercier gloss, and that comes with .11 oz. Yes, there's more gloss in a FREE Mercier sample than there is in a $24 Stila. After using my Stila gloss for about 2 weeks, I was already almost half-way done with it (and I didn't use it every single day) So, to sum up this extremely long review, save your money and buy another gloss that will perform better, last longer, and cost less.
