I have been looking for a shimmer powder for well over a year and could find absolutely nothing until this came along.  I found Jane Iredale's shimmer powder on another website first and ordered there, and then found the gold on Amazon which was what I was really after.  I read one of the reviews about the small size of the powder, but how long it lasts.  I was skeptical, but after using just a bit of this powder, I could see that it's going to last a very long time.  I'm looking into other Iredale products as well to see what other novelties they might have.  Regardless, this is a real winner and will last a very long time.  Beautiful effects.
