Not sure how sparkly
Color: Gold
Smells good, with only a slight chemical part to it that goes away. The sparkle was harder to see, but maybe that’s because it was windy when I sprayed it and it wasn’t very sunny.

Maybe it will arrive. Or maybe not.
Color: Gold
Smells great, but never on time. This time I didn't receive at all, for what I needed.

better results
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
