MAC reflects are pigment glitters that can be used anywhere on the body. Reflects antique gold is so pretty, it's a chameleon sparkle that changes from gold to bronze to green and red.
You can even use pigments in nail polish, and I am itching to try this one with a black nail polish.
I love to use this as an eyeliner color. I just wet my liner brush and it applies like a dream. It works even better with mixing medium. There is always fall out though, which is hard to avoid with any glitter.
