My cousin in England uses a very fine glitter on her cupcakes all the time and it is beautiful. I can't seem to find it here in the states. She uses the brand Rainbow Dust Sparkles which I have only been able to locate online via the UK, Australia and New Zealand - nothing in the US. She has offered to ship me some, but it seems crazy to spend int'l shipping for such an inexpensive item.
The Rainbow Dust Sparkles are a lot different from the glitter I have found online here in the states. The only thing I can find is like a glitter flake and is much larger than the Rainbow Dust. Admittedly, some of the online sources are also a little hard to tell what they would look like on the product.
Didn't know if anyone has used this and/or had luck finding this here in the states (or online that doesn't require int'l shipping). I've seen it on eBay, but it is via England.
I'll attach a couple pics of what my cousin uses and its effect. they come in all sorts of colors.
Thanks for any help!
