Easily Destructed
Color: Green+Orange
My dog destroyed it within a couple of days. The “rope” turned into strings which is dangerous if eaten

Great find!
I used this on a prom bouquet and it came out beautiful. Soft dainty sparkles for the perfect shimmer. A convenient small aerosol container that I gave to my son’s girlfriend in case she wanted to touch it up or use it herself. I love the fact that it’s still stuck on my crafting desk. Very affordable and it served its purpose plus some!

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!
