It's hard to tell how much you get for $20 but it seems like not a lot. I'll have to see how long it lasts. As one of the reviews says it does go on a little clumpy on the bottom but blending takes care of that. No problems on the top lid. I have the dark topaz and the amethyst... I forgot how great the deep purple colors make my eyes look! Now I have to have the ripe plum mascara.
