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!

Color: Glint Pink
I really like the packaging; you don't need to open it and spill everything—with a simple touch, you have the product. I love it and would buy it again.

Not very much dispenses with pumps
Color: Glint Rainbow
This gives out very small puffs of glitter when depressing the pump. The glitter is as expected, but it would be more efficient to just open the dispenser with how little this pumps out. I'll probably just use this for crafts instead of body and hair. It doesnt really stick either because it is a dry powder
