Love it.
Color: Rainy-Rainbow
This glitter is gorgeous on.
Really easy to apply, sprays evenly and a good amount at once. It wasn’t a nightmare to deal with either clinging to things it fell/rubbed onto which I was pleasantly surprised by. It cleans up very well.
A little goes a long way too, so it should last a while. It stayed on my body fairly well throughout the night too.
I have really sensitive skin so I was hesitant to even get glitter at all. I tried body glitter 2 years ago but it was a liquid spray kind and I broke out in an intense rash all over.
I also have a chronic hive condition so my skin flares up from products due to sensitivity.
I did not have ANY issues with this glitter.

Absolutely Stunning Glitter with Thoughtful Packaging! | Rainy Rainbow
Color: Rainy-Rainbow, Color: Rainy-Rainbow
This glitter is breathtaking! The sparkles catch the light very beautifully — it has a mesmerizing, holographic shine that’s perfect for adding extra pizzazz to any project.
When it arrived, I was pleasantly surprised at how well it was packaged. The box was securely sealed, and everything inside was perfectly intact—minor spills, no mess.
A heads up on opening the entire thing: the round container’s Lid is screwed on VERY LOOSELY. Be mindful when you’re unboxing. Screw it back on very tightly.
The spray nozzle on this bottle gives such a beautiful, antique perfume vibe—it really elevates the whole experience. It sprays the glitter perfectly, so it’s easy to get a flawless application every time. (Don’t forget to keep the little nozzle cover to protect it!) Honestly, I wouldn’t apply it any other way than with the bottle—it just makes everything so much smoother. 🤷🏻♀️
If you happen to go overboard, just grab the closest shirt and wipe off any excess. No point in wasting any of this stuff! :)
Oh, & those two little gloss bottles are actually glue, which is perfect for keeping everything right where you need it to be.
Here’s a little pro tip: I used the same tape that kept the box sealed to reseal the lid of the round glitter container until I’m ready to use it.
Worked like a charm! 😎 It’s a small detail, but it will keep everything neat, and prevent unwanted glitter explosions in the future.
If you’re a sparkle lover, you’ll adore this glitter—it’s as pretty in person as it looks online!

Great glitter body spray
Color: Fairy-Diamond, Color: Fairy-Diamond
So cute. Came with extra glitter, I’m assuming lipgloss you can make into glitter lipgloss, a funnel to help pour the glitter. Or re load your spray. The spray performance is nice. Might stick better with some oil before hand? But I like it so far. Worked 6 hours and still had glitter on me for my photoshoot. I sprayed perfume and then glitter. There’s no odor. The amount of quantity of glitter you get seems good for the price. Durability seems good so far but like I said may need some oil or lotion first to help it stick all day.

Troll glitter
Color: Brandy-Rose
Do not spray too much! This glitter is so fine that it dispenses easily from the puff part and you can easily make yourself look like Poppy the troll. We had so much fun with this for prom
