Review (4/5): Transparent powder is awesome; opening of bottle not so much
This is fantastic powder, and I use it to set my makeup when I'm feeling a little more dramatic.
It does exactly what it says, a transparent powder. If you're seeing white patches, you applied too much and haven't spread it out properly. A nice fluffy brush does the trick.
The only reason I don't like this product is that the bottle doesn't really have an easy opening to use a brush with. You'd have to powder it out on a napkin or a piece of plastic, because powdering it out on the inside of the cap won't do because the cap is just too small.
