Sooo pretty in the pan. But, are these super pretty (and pretty pigmented and shimmery metallic) highlighters actually wearable?
Actually, they are wearable. If you want to use them as a highlighter you'll need a light hand, a pretty big brush, and want a bit more of an obvious shimmer in my opinion. It was a bit more "look at me, I have highlighter on" than I typically wear for every day use, though it would be great for going out or a special occasion. Just remember, giant fluffy brush, light application... otherwise I think you risk looking a bit too Jersey Shore.
I actually prefer these for other uses, such as eye shadow. I'm not certain that the pigments are correct for an eye shadow (and yes, pigments are different in eye shadows than in other powder cosmetics), but these are great for that use. They're pigmented enough, they blend well and they last for ages. You can apply them wet for extra intense color as well.
As an alternative, these would be great for Halloween. I'm just throwing it out there.
