    The ultimate festival glow in a bottle!
    **5.0 out of 5 stars - The ultimate festival glow in a bottle!** If you want to be seen from space (in the best way possible), this holographic silver spray is exactly what you need. I bought this for a rave, and it exceeded all my expectations. Unlike other glitters that just look like silver specks, this has a true holographic finish that catches the light and shifts colors beautifully every time you move. The "quick-drying" claim is no joke. I was worried about it feeling sticky or transferring onto my clothes, but it set in about 60 seconds and stayed put. I sprayed it on my hair, my collarbones, and even over my makeup, and it lasted through hours of dancing without fading or raining down "glitter snow" all over the floor. I also love how fine the mist is. It’s a very even, shimmering distribution rather than big, chunky blobs of glitter, which makes it look much more high-end. It washes out of hair and off the skin surprisingly easily with just standard soap and water, too. If you’re looking for that perfect, effortless sparkle for a concert or party, this is the one to get. Just a fair warning: once you start spraying, you'll probably want to cover everything in it!

    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.
