Ever since I discovered MAC products, I've used the eyeshadow exclusively!
Thanks to MAC paints, it stays on all day, and I love the plethora of colors and shades. My favorites are 4-color palletes like one pictured here. You can fill it up with four shades of your choice!
I've got three or four different ones, and am working on filling up a fifth. I am really loving the neutral colors in this limited edition Notoriety palette. Hmmm maybe I will go ahead and add it to my collection! ;)
