Delicate pretty glitter, but pungent
This leaves a beautiful tiny glitter. Beware this glitter will get everywhere and it’s highly perfumed. If you’re smell sensitive or want to avoid getting too much mess, I highly recommend using the spray outside.

Not worth the money
Warning. Don't buy this!!! After shaking the glitter spray, then spraying it on my arm, the stuff comes out in one large clump of small sparkles. You can't even distribute it evenly with your hand. Also, you cannot return the item for a refund unless there was a problem with delivery.

Totally awesome. Get it now
Got this for me and my 5 year old fur Halloween and loved it!! We sprayed it in our hair, on our skin. It was so much fun. It reminded me of the old 80’s glitter hair spray but so so so much more awesome! Get it. Sparkle & shine all over all day and all night *dreamy*
