I've never seen edible glitter on a confection before, and the guests at our 5 year old's party were impressed.  Several asked if they could really eat it.  It doesn't taste like anything, so it's just for looks, but very shiny and cute.  I found them easy to apply, just tap the container lightly, but I don't mind a random effect...they're sprinkles after all, and a little clumping doesn't look bad at all.
